Single Isochrone Fitting

Imagine a file called HUGS1.csv which contains photometry and can be read with pandas for the globular cluster NGC 2808 in your current working directory. Also imagine a directory ISO which contains an isochron in the MIST format. We can fit that isochrone to the photometry as follows

>>> from fidanka.isochrone.MIST import read_iso
>>> from fidanka.fiducual import fiducual_line
>>> from fidanka.isofit.fit import optimize
>>> import pandas as pd
>>> photometry = pd.read_csv("HUGS1.csv")
>>> iso = read_iso("ISO/mist.iso")
>>>
>>> filter1 = photometry["F275W"]
>>> filter2 = photometry["F814W"]
>>> error1 = photometry["F275W_RMS"]
>>> error2 = photometry["F814W_RMS"]
>>>
>>> fiducualLine = fiducual_line(filter1, filter2, error1, error2, reverseFilterOrder=True)
>>> bestFitResults = optimize(fiducualLine, iso, ("F275W", "F814W", "F814W"))
>>>
>>> print(bestFitResults)
