Source Pages¶

This page details the website pages for information on the sources.

Source Query¶

Users can filter and query the sources currently in the database by using the form located on this page.

The form is submitted by clicking the blue :fontawesome-solid-search: button, the red button will reset the form by removing all entered values. Once the form is submitted the results are dynamically updated in the results table below the form (i.e. on the same page).

The following sections provide further details on the form.

Data Source¶

Here a specific pipeline run can be selected from a dropdown list to filter sources to only those from the chosen run. By default sources from all runs are shown.

Cone Search¶

Users can choose whether to input their coordinates directly or use the object name resolver to attempt to fetch the coordinates.

Manual Input¶

The format of the coordinates should be in a standard format that is recognised by astropy, for example:

• 21 29 45.29 -04 29 11.9
• 21:29:45.29 -04:29:11.9
• 322.4387083 -4.4866389

Galactic coordinates can also be entered by selecting Galactic from the dropdown menu that is set to ICRS by default. Feedback will be given immediately whether the coordinates are valid, as shown in the screenshots below:

Once the coordinates have been entered the radius value must also be specified as shown in the screenshot above. Use the dropdown menu to change the radius unit to be arcsec, arcmin or deg.

Name Resolver¶

To use the name resolver, the name of the source should be entered into the Object Name field (e.g. PSR J2129-04), select the name resolver service and then click the Resolve button. The coordinates will then be automatically filled on a successful match.

if no match is found then this will be communicated by the form as below:

Table Filters¶

This section of the form allows the user to place thresholds and selections on specific metrics of the sources. Please refer to the Source Statistics page for details on the different metrics. There are also tooltips located on the form to offer explanations.

The following options are not standard source metrics:

Include and Exclude Tags¶

Users can attach tags to sources (see Source Tags and Favourites) and here tags can be selected to include or exclude in the source search.

Source Selection¶

Here specific sources can be searched for by entering the source names, or source database id values, in a comma-separated list. For example:

• J011816.05-730747.77,J011816.05-730747.77,J213221.21-040900.42
• 1031,1280,52

are valid entries to this search field. Use the dropdown menu to declare whether name (default) or id values are being searched.

Results Table¶

Located directly below the form is the results table which is dynamically updated once the form is submitted. The full detail page of a specific source can be accessed by clicking on the source name in the table. Explanation of the table options can be found in the DataTables section.

Source Detail Page¶

This page presents all the information about the selected source, including a light curve and cutouts of all the measurements that are associated to the source.

Star, SIMBAD, NED, Previous & Next Buttons¶

These buttons do the following:

• Star: Adds the source to the user's favourites, see Source Tags and Favourites.
• SIMBAD: Performs a cone search on SIMBAD with a radius of 10 arcmin centered on the source location.
• NED: Performs a cone search on NED with a radius of 10 arcmin centered on the source location.
• Previous: Navigates to the previous source that was returned in the source query.
• Next: Navigates to the next source that was returned in the source query

Details¶

A text representation of details of the source, including position, number of measurements and whether the source is defined as new.

First Detection Postage Stamp¶

Shown in this panel is a postage stamp of the first detection of the source in the pipeline run. Postage stamps of all measurements can be seen in the main postage stamp section lower on the page.

Aladin Lite Viewer¶

Aladin Lite Documentation.

The central panel contains an Aladin Lite viewer, which by default displays the HIPS image from the Rapid ASKAP Continuum Survey, centred on the location of the source. Other surveys are available such as all epochs of the VAST Pilot Survey (including Stokes V) and other wavelength surveys such as 2MASS.

Flux & Variability Details¶

The flux details, both integrated and peak, of the source. Also shown are the variability parameters calculated by the pipeline.

Light Curve¶

The light curve of the source is shown. The peak or integrated flux can be selected by using the radio selection buttons.

Two-epoch Node Graph¶

The node graph is a visual representation of what two-epoch pairings have significant variability metric values. If an epoch pairing is significant then they are joined by a line on the graph. Hovering over the line will highlight the epoch pairing on the light curve plot.

External Search Results Table¶

This table shows the result of a query to the SIMBAD and NED services for astronomical sources within 1 arcmin of the source location. Along with the name and coordinate of the matches, the on-sky separation between the source is shown along with the source type.

User Comments & Tags¶

Users are able to read and post comments on a measurement using this form, in addition to adding and removing tags, see Source Tags and Favourites.

JS9 Viewer Postage Stamps¶

JS9 website.

The JS9 viewer is used to show the postage stamp FITS images of the measurements that are associated with the source, loaded from their respective image FITS files.

Source Measurements Table¶

This table displays the measurements that are associated with the source. The detail page for the measurement can be reached by clicking the name of the respective measurement.

Related Sources Table¶

This table displays the sources that are a relation of the source in question. For further information refer to the Relations section in the association documentation.
