Aside - A couple weeks ago Brandon Basso complained that my buzzing wasn't frequent enough. He requested more plots and perhaps an update on Adam's research. Well ask and you shall receive! Brandon this plot-heavy post is dedicated to you.
I am trying to understand why we seem to be missing objects around u-g = 0.8. Joe suggested I make the color plots in different redshift bins. So here we go. Warning, there are a lot of plots.
First, let me show you a temperature plots of the different luminosity functions. Below are color-color diagrams where the color of the points changes as a function of redshift in the following way:

First, let me show you a temperature plots of the different luminosity functions. Below are color-color diagrams where the color of the points changes as a function of redshift in the following way:
dark red = 1.0 < z < 1.2
red = 1.2 < z < 1.4
orange red = 1.4 < z < 1.6
orange = 1.6 < z < 1.8
gold = 1.8 < z < 2.0
lawn green = 2.0 < z < 2.2
lime green =2.2 < z < 2.4
dark green = 2.4 < z < 2.6
teal = 2.6 < z < 2.8
dodger blue = 2.8 < z < 3.0
royal blue = 3.0 < z < 3.2
blue = 3.2 < z < 3.4
navy= 3.4 < z < 3.6
dark slate blue = 3.6 < z < 3.8
dark orchid = 3.8 < z < 4.0
red = 1.2 < z < 1.4
orange red = 1.4 < z < 1.6
orange = 1.6 < z < 1.8
gold = 1.8 < z < 2.0
lawn green = 2.0 < z < 2.2
lime green =2.2 < z < 2.4
dark green = 2.4 < z < 2.6
teal = 2.6 < z < 2.8
dodger blue = 2.8 < z < 3.0
royal blue = 3.0 < z < 3.2
blue = 3.2 < z < 3.4
navy= 3.4 < z < 3.6
dark slate blue = 3.6 < z < 3.8
dark orchid = 3.8 < z < 4.0
As a reminder here are the luminosity functions I am using:
The above plot shows several luminosity functions.Green is Richards 06, cyan is Jiang, purple is Jiang Combined (what we used in previous QSO Catalog, white is a Richard/Jiang average (suggested by Myers).
Here are the color-color redshift temperature plots for the QSO Catalogs generated by the above luminosity functions (click plots on below to make larger):
Also I have made color-color plots binned by redshift separately. I've done them for all of the luminosity functions, but they all look pretty much the same, so I'll just post them here for the Richards function (green luminosity function above), the redshift range is in the main title of the plots:
Here are some histograms of various quantities for the different luminosity functions the color scheme is same as above, Green is Richards 06, cyan is Jiang, purple is Jiang Combined (what we used in previous QSO Catalog, white is a Richard/Jiang average:
redshift
Color-band psffluxes
Color-band magnitudes
Color-band magnitudes
Color-color plot u-g/g-r
Hopefully that is enough plots for Joe to see what is going on with these QSO catalogs and Brandon to be satisfied.
Oh and here is an update on Adam's research (check out his shirt).
