Fiducial Measurement


from fidanka.fiducial import measure_fiducial_lines

MC = 1000
fiducialLine = measure_fiducial_lines(
        photometry["F275W"],
        photometry["F814W"],
        photometry["F275W_RMS"],
        photometry["F814W_RMS"],
        reverseFilterOrder=True,
        mcruns=MC,
        nPops = 2
        )

Dynamic ~~Time~~ Magnitude Warping

Isochrone Optimization


from fidanka.isochrone.MIST import read_iso
from fidanka.isofit.fit import optimize

MISTIsochrone = read_iso("ISO/mist.iso")
popAFiducial = fiducialLine[0]

bestFitResults = optimize(
    popAFiducial.mean,
    MISTIsochrone,
    bolometricCorrectionTablePaths,
    FeH,
    filters = ("F275W", "F814W", "F814W")
)
