Citizen GBOT Upload

On this service, you are welcome to upload images taken of the Gaia spacecraft during the XY (url) campaign.

Only FITS images with standard space calibration (WCS) are accepted. If you do not know how to calibrate your images, see https://astrometry.net/use.html.

We also require the following headers:

• DATE_OBS containing a UTC timestamp of the form YYYY-mm-ddTHH-MM-SS. If than means anything to you, prefer the GPS timescale.
• FILTER containing a free text describing any filters that you used. Say “clear” for optical observations without any filters.

We ask you to include the following headers:

• SITELONG, SITELAT, SITEELEV: geographical coordinates, elevation above some reasonable definition of sea level
• CONTACT: some way to contact you. Note that this will be public (although we do not expect spammers to harvest FITS files); do not use valuable contact data here. It is unlikely that we will try to contact you after, say, April 2025.
