FitsArray.ccdproc(self, master_zero: Fits | None = None, master_dark: Fits | None = None, master_flat: Fits | None = None, exposure: str | None = None, output: str | None = None, force: bool = False) → Self

Performs CCD correction on the FITS data using provided calibration files.

Parameters

master_zeroOptional[Fits]

The zero file to be used for bias correction.

master_darkOptional[Fits]

The dark file to be used for dark correction.

master_flatOptional[Fits]

The flat file to be used for flat-field correction.

exposureOptional[str]

The header card containing exposure time (exptime).

outputOptional[str]

New path to save the corrected files.

forcebool, default=False

If True, forces the correction even if it results in overcorrection.

Returns

FitsArray

A CCD-corrected FitsArray object.

from myraflib import FitsArray, Fits

fa = FitsArray.sample()

master_zero = Fits.sample()
master_dark = Fits.sample()
master_flat = Fits.sample()

calibrated_fa = fa.ccdproc(master_zero=master_zero, master_dark=master_dark, master_flat=master_flat)
