This represents the best fit that I've been able to generate for the pksmb pulsars with logB > 10 actual results

DM

The main issue with this is there is a peak at 550-600.

P

There are some long period pulsars generated. They are all shown above.

This graph shows just the P < 10s pulsars. The peak isnt as high as the real data and the distribution looks wider.

LogB

Should be loaded more into the 12.

notes

Trying to correct the issues with these graphs has limited success. I can make the P of LogB fit more closley but the DM histogram gets further from the survey data.

PKS70

spectral index changed to 1.1 to get the number of pulsars correct for the pks70 survey correct.
