[lsst-dm-stack-users] Matching DC2013 stack results with SDSS Stripe82

[VULPESCU Bogdan]

Hello,

After the exercise of the Data Challenge during the summer of 2013 at 
the Computing Center in Lyon, France
(CCIN2P3), I am trying to understand the results of the stack in terms 
of a comparison with the released SDSS
results using the same input data. I have extracted all the entries from 
the PhotoObj view of the CAS DB server for
Stripe82 and I am starting on a small region (a patch, somewhere in the 
overlap region between the CCIN2P3 and
NCSA of the DC2013). I understand that in my analysis I have to do 
certain quality selections on both sides, such as
the different flags for the deep coadd sources. Does anyone have an idea 
of how to obtain from the two lists comparable
items? I have a limited knowledge (not being a specialist) about the 
meaning of some of the columns in the deep coadd
source table and the same for the SDSS tables, although I am trying to 
understand the descriptions from their schema
browser.
Thank you for any help you could provide.

best regards,

    Bogdan.
