DESI footprint overlay for a specific tile id number

Could we please add the option of creating the DESI footprint overlay for a specific DESI tile ID number? That would be super useful. Perhaps this could be done just in the “Jump to object” box by typing something like “tile 56816” or something. Thanks!

#32 Might be relevant :)

So that Arjun doesn't have to read N>>1 comments to find the syntax, try typing "DESI 4" (with a space) in the "Jump to object" box, or directly construct URLs like

Hi Mark, This is very nice, but the remaining problem is that the Commissioning/SV tile numbers are not included. I just tried: http://legacysurvey.org/viewer?desi_tile=56816&layer=dr8&desifoot&desifiber&zoom=8 <http://legacysurvey.org/viewer?desi_tile=56816&layer=dr8&desifoot&desifiber&zoom=8> and it took me to a region with the wrong coordinates.

Hi Arjun,

I guess this could be achieved by updating the desi-tiles.fits file on NERSC. I'll double check with Stephen.

Adding commissioning tiles would be great, but let's not do that until we've converged on what the commissioning tileid,ra,dec will be (and use old-school ra,dec in the meantime for vetting proposed cmx tile locations).

@arjundey where did you get "56816" from? Since that is part of the "extra" layers of the standard desi tiling, that should not be included in any CMX tile lists. The commissioning instrument started at 58000, standard commissioning should be in the 60k range (or at least 59k+), and SV is in the 70k range.

Note that the viewer is loaded with the tiles in $DESIMODEL/data/footprint/desi-tiles.fits, which is not Eddie's proposed tiling pattern which is still a bit in flux.

Dear Stephen and Mark, 56816 came from my addled brain - i meant 58616. Mea culpa. I agree we should wait until we have converged on the final set of commissioning / SV tiles. Thanks! Arjun
