ColortermDict

class lsst.pipe.tasks.colorterms.ColortermDict(*args, **kw)

Bases: Config

A mapping of physical filter label to Colorterm

Different reference catalogs may need different ColortermDicts; see ColortermLibrary

To construct a ColortermDict use keyword arguments: ColortermDict(data=dataDict) where dataDict is a Python dict of filterName: Colorterm For example: ColortermDict(data={

‘g’: Colorterm(primary=”g”, secondary=”r”, c0=-0.00816446, c1=-0.08366937, c2=-0.00726883), ‘r’: Colorterm(primary=”r”, secondary=”i”, c0= 0.00231810, c1= 0.01284177, c2=-0.03068248), ‘i’: Colorterm(primary=”i”, secondary=”z”, c0= 0.00130204, c1=-0.16922042, c2=-0.01374245),

}) The constructor will likely be simplified at some point.

This is subclass of Config. That is a bit of a hack to make it easy to store the data in an appropriate obs_* package as a config override file. In the long term some other means of persistence will be used, at which point the constructor can be made saner.
