Parameterize fiberloss #11

Open sbailey opened 9 years ago

sbailey commented 9 years ago

Currently the fiber input geometric losses are treated as being the same for all objects of a given objtype -- i.e. the loss for the median size for that object under median seeing conditions. This really should be a function of seeing, object size, object profile, and fiber mis-centering. Find a way to efficiently parameterize that and a data model to store it.

The inputs to throughput should then include seeing, objsize, and fiber offsets in addition to objtype.

objsize: pick a name that makes it clear if this is radius, FWHM, diameter, etc.

profile: should support Gaussian, Moffat, and Sersic with various n (de Vaucouleurs, exponential).
