LSDR10: Please could you provide more details re: "psfdepth_*"?

Question

Hiya again,

I've been trying to understand the psfdepth_* columns that are output when crossmatching with LSDR10. I've read https://www.legacysurvey.org/dr10/description/#psf but it is not mentioned. Perhaps someone more familiar with SExtractor and PSFex is able to help? E.g. what units are these columns in? 

The psfsize_* columns are more intuitive as the numbers are all deviations above/around 1.00.

Thanks,

Sarah

P.S. It's OK! I've just found the appropriate webpage: https://www.legacysurvey.org/dr10/files/#tractor-catalogs-south-tractor , which explains the numerous columns!
