Changing QSO Catalog Inputs

I'm trying to figure out how to modify the inputs (currently SDSS DR5 quasars with good photometry) into Joe's Monte Carlo. Here is what I have figured out so far (all the below files are on riemann): ;main program to generate the QSO Catalog
(calls) → ;generates simulated redshift and i-magnitude based on luminosity function and DR5 inputs
(calls) → ;This generates the training set photometry
(calls) → ;This reads in SDSS data it currently has the following 'DR5' call
qsos = sdss_read_data('DR5', Z_MIN = Z_MIN, Z_MAX = Z_MAX)

Here is a color-color redshift temperature plot of these DR5 QSOs:

I'm going to try to add in the BOSS QSOs with co-added photometry, especially in the redshift range z > 2.0 where we seem to be missing QSOs:

I found that there are 1,973 BOSS quasars that have a redshift above 2.0 for which we also have coadded photometry. Here they are plotted:

While it is a little more filled in in the u-g = 0.8 space, comparing it to all the BOSS quasars (regardless of how good their photometry is) below:
