Add FoV as a parameter

[aboucaud]

I think the field of view would be a nice value to have in galcheat, even though not useful at the BTK level.

What do you think @ismael-mendoza, @HironaoMiyatake @mpaillassa ?

[ismael-mendoza]

Sorry, could you give more details on what you mean by field of view in the context of galcheat? Is it like the extent of each survey ?

[aboucaud]

I mean the footprint of a single exposure of the survey on the sky. We could also add the full area covered by the survey.

[ismael-mendoza]

yeah I think that would be useful actually, I remember people in the BL meeting were saying that would like to have that. What do you think @mpaillassa ?

[ismael-mendoza]

In fact I have some notes from the BL meeting some months ago suggesting:

Location for survey footprints, whether two surveys have any overlapping region? or some approximation to them (arcseconds)

[mpaillassa]

Yes I think it could be nice to have both. I propose a definition and different names for each:

• Area covered by a single frame/exposure or by the CCD mosaic: field of view, field size, field area.
• Area covered by the survey: survey area, survey size, survey (sky) footprint.

With the second we can then imagine having a small script to display the survey areas or compute overlap regions between surveys.
