CDS is actively participating in the #ADASS2024 conference in Malta this week. On Tuesday, Sébastien Derriere presented work on improving links between the IUE observation log and the SIMBAD database.

Pooja Sharma made a video version of the tutorial that was given at the IAU 2024 "VO workshop for African astronomers" side-event. It is available on YouTube (https://youtu.be/2dC1R7PnuU4) and POD (https://pod.unistra.fr/video/57005-introduction-to-the-main-cds-services/)

Our mystery object was Saturn (and its moons) !

Can you find the other location in the VPHAS DR4 survey where Saturn was also observed ? (with a different date and location, of course)

Let us know if you find this format of mini tutorials in threads useful !

[12/12]

The intersection spans only a few minutes of time, on 2017-07-26, between 02:52:50 and 02:58:23.

We can use the IMCCE SkyBot tool (`Ctrl+L > IMCCE SkyBot` tab on the right), enter the median date and time and search for solar system objects around these coordinates at the time of the observations.

[11/12]

Compute the intersection of the two STMOCs from the menu `Coverage > Logical operations...`, select the two STMOCs and CREATE the intersection in space and time.

[10/12]

In the properties of this new MOC (Moc reg), add a Time range corresponding to that of the VPHAS DR4 : 2011-12-29T00:00:00 - 2018-08-12T23:59:59.

[9/12]

With the "phot" tool, select the region around the mystery source, and convert this selection into a MOC with `Coverage > Generate a spatial MOC based on... > The selected drawing object`.

[8/12]

Select the VPHAS HiPS plane, and load its STMOC coverage. This is the space-time coverage description of the VPHAS survey, describing when each image used in the HiPS was observed.
