Extracting point sources from Slices

We again start out with having a project open called proj:

>>> proj = GMOSMOSProject(dbname, work_dir=work_dir, echo=False)

Calculating Slice Geometries

Sources in the Database

For this to work the database has to be constructed and has linked the science sets together. Each slice is associated with a number of MOSPointSources. These objects hold information about the priority and the slit position for the current slice. Having a slice object it is easy to access the associated MOS Point Sources:

>>> slice = proj.science_sets[0].slices[0]
>>> mos_ps = slice.mos_point_sources[0]
>>> mos_ps
<MosPointSouce id=25036361 priority=0 slit position=0.0000>
>>> mos_ps.slices
[<GMOS MOS Slice lower_edge=741.76 upper_edge=755.46)>]
