Accessing DR10 inverse variance maps

[Adam Watts]

Hi legacy team, 

I am looking, with not much success, for the 1/rms^2 maps for the coadded g-/r-/i-/z- band Legacy survey images. The use case is for estimating errors in broadband photometry fitting for, e.g., stellar mass estimates. Any advice on how to access/download them wold be much appreciated :)

Kind regards,

Adam

Hi,

We call these "invvar" (inverse-variance) maps, listed here

https://www.legacysurvey.org/dr10/files/#image-stacks-south-coadd

and available with the rest of the "coadd" data products, eg here

https://portal.nersc.gov/cfs/cosmo/data/legacysurvey/dr10/south/coadd/000/0001p000/legacysurvey-0001p000-invvar-g.fits.fz

for brick 0001p000 in g band.

cheers,

dustin
