Recent Updates

10/12/2017Set 8,153 duplicated observations to deleted status. Matching criteria used to identify duplicates:
Julian Date (exact)
Variable Designation
23/04/2017Added new page on star name conventions with a link on the upload screen and homepage.
22/02/2017Fixed issue with + being interpreted as a space character in object ids when selecting the object summary in the variable star list. Fixed by replace + characters with %2b in the hyperlink.
01/01/2017Amended observation download to use pipe character | rather than new line between the different CCD measurements in a single observation. Also fixed a bug with downloading data with Firefox where the filename would be truncated at the first space. Due to Firefox only recognising a filename string enclosed by double quotes.
17/09/2016Implemented new data download functionality. Observation download button now moved to main data screen. Additional fields added to table and download.
14/09/2015Removed data download functionality due to issue.
29/08/2015Amended the sequence data screen from showing the full 4 decimal places in the database table, to showing a truncated 3 decimal places.
Changed sequence table column width by removing table setting to be across the whole screen.
12/08/2015In the single and bulk observation edit screens, replaced the variable star list used when selecting observations with the main object_id rather than the object_alias. Left the variable that is entered/updated as the object_alias since this must match the observation table.
09/08/2015Behind the scenes changes released to enhance the magnitude recalculation prototype pages.
01/08/2015Behind the scenes changes released to enable the prototyping of the magnitude recalculation pages.
28/06/2015Added link to the database statistics page for logged in users. The link can be found on the homepage under the General heading.
28/12/2014Optimisation of the upload process to get it to run more quickly and hopefully avoid 60 second timeouts on the web. Modified the procedure that first uploads the data to the temporary tables so that the estimates and measurements tables are only hit the once. Modified the commit process to run 1 rather than many delete commands on each of the temporary tables.
10/12/2014Altered order of displayed and exported data table from ascending Julian date to descending Julian date.
20/10/2014Further modification to the JavaScript that is used to convert UT to JD in the Review Data page. The conversion had stopped working in Google Chrome giving NaN rather than a number.
19/10/2014Modification to the JavaScript that is used to convert UT to JD in the Review Data page. The conversion had stopped working in Google Chrome giving NaN rather than a number.
17/10/2014Correction to observer summary by star. Sometimes zero magnitude was being returned for the first or latest magnitude when it should not have been.
03/08/2014Added optional start and end Julian Date to the database summary page.
14/06/2014Added instrument and camera under the heading of equipment to the data table page from review data for a star.
26/05/2014Modified 986 observations and 354 star alias names to remove multiple spaces from names. These were interfering with the operation of some web pages.
26/05/2014Modified data entry cleaning to strip out all multiple spaces and replace with single space. Multiple spaces had been causing problems between the database and web pages, since HTML strips out multiple consecutive space characters to display only single spaces on the screen.
22/05/2014Added filter to the summary of uploaded observations page.
13/05/2014Update to new column "Estimates / Comparison Stars" to improve formatting. The separator between multiple estimates and comparison stars is now a semi-colon and the text is preceded by a space so that Excel will not try to interpret estimates as formula or dates.
09/05/2014Added new columns "Estimates / Comparison Stars" and "Chart / Sequence" to the data table produced by the light curve generator.
06/05/2014Corrected mistake in the Year and Month summaries by Observer, Star and the whole database. The Julian Date was not being correctly converted to UT, but was often giving a date a day in the future of the true date.
04/05/2014Added options of 'Instrumental-Transformed' and 'PreCalculated-Transformed' for entry of CCD data. 'Instrumental-Transformed' has a different error tolerance on the magnitude check as the check cannot transform the data.
30/04/2014Added check on visual file upload to make sure hour does not contain a decimal.
23/04/2014Modified visual upload so that the estimate is not mandatory.
18/04/2014Tweaked the visual upload magnitude tolerance from <=0.05 to <=0.099 magnitudes to cope with magnitudes uploaded to 2 decimal places.
17/04/2014Tweaked the visual upload magnitude tolerance from <0.05 to <=0.05 magnitudes to cope with magnitudes uploaded to 2 decimal places.
15/04/2014Released star summary web page including count of observations by year and month and count of observations by observer. This can be accessed by clicking the Object Id hyperlinks in the Variable Stars standing data page.
14/04/2014Released enhanced observer summary including count of observations by year and month.
10/04/2014Further update to filter colours in the light curve generator to make them more distinct.
09/04/2014Updated and standardised filter colours in the light curve generator to make them more distinct from one another, except when they are for similar filters.
05/04/2014Fixed bug with web pages for editing variable star names and alias names. They were not allowing the star names or alias names to be updated with new names.
22/03/2014Changed default dates in the Light Curves to UT rather than JD.
22/03/2014Enhancements to the date check in the upload program so it will work for pre-1900 dates.
11/03/2014Database updated with all Visual and CCD observations received to date.
09/03/2014Fixed bug with 'Manual Enter Observations' screen. Observations were being added but the observation variable was being accidentally passed between procedures due to variable scope. This showed as an erroneous additional measurement for Visual observations.
06/03/2014Enhanced UT calculation to check for valid hour and minute values.
02/03/2014Added options to filter bulk observation edit by Sequence and Location, including "BLANK" sequence and location. Also fixed a bug introduced by this change to the individual observation edit screen, and moved the fetch and reset buttons to the left hand side.
28/02/2014Enhancement to UT display on light curve so that hh:mm is only shown for periods of 5 days or less. Note this does not work when zooming as the date format is fixed when the light curve is created.
Also made minor fix to selection page as the Reset had stopped working with the change on the 27th Feb. This should now work again.
27/02/2014New buttons on light curve and data table to modify selection parameters.
23/02/2014Added link to BAAVSS homepage in top left corner when on the BAAVSS Database homepage. Also made the link to the BAAVSS homepage more prominent in the General section by moving it to the top of the section.
23/02/2014Modified default of 5 estimates per visual observation in Manual Observation Entry screen to a default of 1 estimate per observation.
22/02/2014Release of version 2 of the website, to enable observers to upload and edit their own observations.
25/10/2013Preliminary version 2 website complete. This includes ability for users to load their own data.
24/08/2013Uploaded 2011 and 2012 observations from the visual database. This includes a lot of historic observations as well as those received during 2011 and 2012. In total 117,070 new observations.
10/08/2013Uploaded CCD observations received by 10th August 2013.
14/04/2013Uploaded CCD observations received by 31st March 2013.
24/02/2013Fixed minor bug with filtering on a star. After applying the filter any text after a space in the filter by box was being removed. Now all text is retained.
27/10/2012Uploaded CCD observations received by 27th October 2012.
19/08/2012Corrections to 2,621 Julian Dates pre 1900.
29/04/2012Minor changes to light curve page.
Moved reset zoom above chart title so this can be cut out of screen prints.
Added link to new page of fixes to known light curve issues.
14/04/2012Minor change to End Date Julian Date calculation in Review Data sheet.
Adds 1 day to quoted UT so the JD is the end of that day. E.g. enter 31st May as UT and JD will be calculated as start of 1st June.
09/04/2012Corrected 304 CCD observations with reported magnitude problems.
09/04/2012Uploaded CCD observations received by 6th April 2012.
20/03/2012Light curve legend moved to bottom left hand corner. It is the intention that users will be able to relocate the legend themselves in a future release.
11/03/2012Set 14,213 duplicated observations to deleted status. Matching criteria used to identify duplicates:
Julian Date (not just matches but must be recorded to at least 4 decimal places to avoid accidental removal of observations made at similar time but full time not recorded)
Variable Designation
Only 2 or 3 duplicates (there are a small number with many duplicates. These will be checked separately.)
19/02/2012Major update to variable designations and alias designations.
31/12/2011Created page for list of recent updates.
31/12/2011Added summary page of observer's observations. Accessed by pressing Observer Id hyperlinks in observer list.
31/12/2011Added download buttons to list tables.
31/12/2011Split observer names into surname and initials.
30/12/2011Created filter button on data page to allow users to search and filter the list of variable stars. Note this also searches the full list of alias names held within the database.
29/12/2011Loaded all CCD data received to date.
