Description
For binaries or pulsars a typical task is to fit the source spectrum for different phases. A ctool should be written for this task. Phase information will already have to be added to the events file beforehand. All sources besides the periodic source have no phase dependency.
Recurrence
No recurrence.

The code is now working (for me). To test it there is an example events file with events information in test/data/phased_events.fits.
from cscripts import *
phrv = csphasecrv()
phrv.execute()
In the way it is currently implemented the code works only for pulsars (or generally the source period needs to be smaller than the time for exposure changes). The flux normalizations in the time component of the source model are renormalized to the phase fraction. Note that in the current version the non-source components are also fitted independently in each phase. In the future is would be nice to tie them in the fit over all phases.

I added a unit test for csphasecrv and integrated the script into the ctools. Also a reference manual page exists.
The code has been merged into devel.
