New Threshold Results

I've calculated the (new) thresholds using the method outlined in this post.

Below are the lratio new thresholds for the old version of the likelihood (v1) and the likelihood with ALL the Quasars as a function of targets per square degree (TPSD):

TPSD ----- v1 threshold - all quasar threshold
10.0000 -----0.749085 --------- 0.770306
20.0000 -----0.490932 --------- 0.571854
30.0000 -----0.347334 --------- 0.425242
40.0000 -----0.253020 --------- 0.329808
50.0000 -----0.198630 --------- 0.264506
60.0000 -----0.160074 --------- 0.214092
70.0000 -----0.128912 --------- 0.182231
80.0000 -----0.107913 --------- 0.152691

Here's a plot
Cyan is the ALL the Quasars
Green is likelihood v1


Using these thresholds here are the number of quasars targeted:
TPSD ---- #QSOs (v1) --- #QSOs (ALL Quasars)
10.0000
---443.000 -------- 406.000
20.0000
---656.000 -------- 582.000
30.0000
---781.000 -------- 722.000
40.0000
---897.000 -------- 830.000
50.0000
---965.000 -------- 892.000
60.0000
---1035.00 -------- 955.000
70.0000
---1089.00 -------- 1000.00
80.0000
---1123.00 -------- 1037.00

Here's a plot
Cyan is the ALL the Quasars
Green is likelihood v1

Looks like ALL the quasars doesn't do better after all with the non-Milky Way thresholds. Boo.
The log file to run this code is here: ../logs100520log.pro
