7 years ago Hi Jenny - each row in the table specifies a lens system. A lens system
has both lens (galaxy) and source (quasar) properties. The term "lenses" in
the OM10 code typically refers to a lens system. The sample that you
select is a subset of the main table: each item in the sample is a lens
system. To pull out the quasar source information only, just ask for the
quasar properties!

Good Evening @drphilmarshall https://github.com/drphilmarshall!
I remember that there are mixtures of lenses and quasars in the qso_mock.fits file. I am not totally sure whether we talked about this in the meeting, but are there any recommended methods that I could use to just pull out only the quasars? All the rows have ZSCR and MAGI_IN greater than zero( i.e. db.sample[db.sample['ZSRC']<0] and db.sample[db.sample['MAGI_IN']<0] both return zero). I thus thought of choosing quasars from lenses based on the i band magnitude distributions, but I was wondering whether there would be a better way to choose quasars.
Thank you so much!
