Overview

The standing data screen gives access to the data tables that underpin the BAAVSS observation database. From these screens you can:

·         Search all the designations which have been setup for a star.

·         Locate and view the summary of an observer.

·         Review sequence setup and magnitudes.

If you find any errors with the data then please email the database manager. A link to the database manager’s email address is on the homepage of the database website, and can also be found on the back cover of the VSS Circulars.

Variable Stars

This screen allows you to access the full list of variable stars which are in the database. This is a list of the primary designations only, so each star appears just once with the name that appears on Light Curves.

·         The list can be filtered by typing values into the boxes at the top and pressing the “Apply Filter” button.

·         The data that is shown on the page, be it the full list or a filtered list, can be downloaded as a csv file (commas separated values) by pressing the Download Data button.

 

Columns

·         Object Id – The primary designation for a variable star in the database.

·         Constellation – The 3 character abbreviation for the constellation.

·         Comment – Any pertinent information to the variable star or its setup within the database.

·         Last Modified – The date and time at which the setup of this star was last changed.

·         Validated – Whether or not this star has been reviewed and approved by a VSS Officer.

o   As stars can be created by uploading observations any new stars will at first be unvalidated.

·         AUID – The AAVSO id for the star.

Star Alias Names

The star alias names screen lists all the different names by which a variable star is known in the database. The Object Id is the primary id for the star, while the object alias gives the alias name for the star. So there can be many Object Alias’ for a single Object Id.

·         The list can be filtered by typing values into the boxes at the top and pressing the “Apply Filter” button.

·         The data that is shown on the page, be it the full list or a filtered list, can be downloaded as a csv file (commas separated values) by pressing the Download Data button.

Columns

·         Object Alias – Any name by which a star may be known.

·         Object Id – The primary name by which the star is known in the database. This is the star name that will appear on Light Curves.

·         Last Modified – The date and time at which the object alias was last changed.

·         Validated – Whether or not the Object Alias has been reviewed and approved  by a VSS Officer.

o   As new stars can be created by uploading observations, at first all new stars will be unvalidated.

Observers

This screen lists all the observers who are setup within the database.

·         The list can be filtered by typing values into the boxes at the top and pressing the “Apply Filter” button.

·         The data that is shown on the page, be it the full list or a filtered list, can be downloaded as a csv file (commas separated values) by pressing the Download Data button.

Columns

·         Observer Id – The unique id for the observer within the database.

o   The Observer Id is a hyperlink which will take you to a summary page for that observer.

·         Observer Name – The full name of the observer.

·         Initials – The initials of the observer

·         First Name

·         Middle Names

·         Surname

·         Comment – Any comment on the observer held within the database.

Observer Summary

Clicking on an Observer Id in the Observers screen will take you to a summary page for that observer.

Sequence List

This is a list of stars that have sequences.

·         The list can be filtered by typing values into the boxes at the top and pressing the “Apply Filter” button.

·         The data that is shown on the page, be it the full list or a filtered list, can be downloaded as a csv file (commas separated values) by pressing the Download Data button.

Columns

·         Sequence Id – A unique number used to identify the sequence.

·         Object Id – The variable star which the sequence has been created for.

·         Latest Sequence Version – The number of the sequence version which is the latest approved sequence. This is the sequence that will be used when recalculating observation magnitudes to the latest sequence.

·         Old Sequence File – The file name from the old visual database.

Sequence Versions and Alias Names

This is a list of all the different versions of sequences, along with the different alias names that an individual sequence version may be known by. Each sequence may have multiple versions, and each version may have multiple Sequence Alias names.

·         The list can be filtered by typing values into the boxes at the top and pressing the “Apply Filter” button.

·         The data that is shown on the page, be it the full list or a filtered list, can be downloaded as a csv file (commas separated values) by pressing the Download Data button.

Columns

·         Sequence Id – The unique number used to identify the sequence.

·         Object Id – The variable star for which the sequence was created.

·         Sequence Version – The version number for the sequence.

·         Sequence Alias – A name by which the sequence version is known.

·         Primary Alias – Yes to indicate this is the name to be used for a sequence version when the sequence is displayed.

Sequence Data

This screen allows you to pick a sequence and view the entire sequence along with all versions in a table.

·         Fetch Sequence will create a table of the sequence data.

·         Download Data will download the table of sequence data to a csv file (comma separate values).

·         The magnitude for a given comparison star may vary across the table as more accurate measurements of the magnitude were obtained for subsequence sequence versions.

Columns

·         Comp No. – The comparison star number. Cells are coloured grey and are at the left and right of the table.

·         Sets of columns by Sequence Version – Note the sequence version has the version number followed by the Primary Alias

o   Comp Alias – The alias name by which the comparison star is known. Note sometimes there will be multiple columns for alias names where a comparison may be known by more than one name.

o   Mag – The magnitude of the comparison star for the sequence.
