Module obsbandpass

source code

The ObsBandpass user interface needs to support either the usual (acs,hrc,f555w) obsmode style that produce a set of chained throughput files; or something like (johnson,v) that has a single throughput file. Thus ObsBandpass must be a factory function, returning either an ObsModeBandpass (ack, terrible name) or a TabularSpectralElement.
