Functions

`fit_ramps_mcds`(times, ramps[, num_coadd])	Fits ramps using the (M)CDS method.
`fit_ramps_ols`(times, ramps)	Top-level function for fitting ramps.

liger_iris_pipeline.readout.fit_ramp_numba.fit_ramps_mcds(times, ramps, num_coadd=1)[source]

Fits ramps using the (M)CDS method.

Args:: times (np.ndarray): Read times. ramps (np.ndarray): 3D array of ramp data with shape (ny, nx, n_reads, n_groups). num_coadd (int): Number of coadds. num_coadd=1 for CDS.
Returns:: dict[str, np.ndarray]: Dictionary with keys ‘slope’ and ‘slope_err’ containing the fitted slopes and errors.

liger_iris_pipeline.readout.fit_ramp_numba.fit_ramps_ols(times, ramps)[source]

Top-level function for fitting ramps.

Args:: times (np.ndarray): Read times. ramps (np.ndarray): 4D array of ramp data with shape (ny, nx, n_groups, n_reads).
Returns:: dict[str, np.ndarray]: Dictionary with keys ‘slope’ and ‘slope_err’.
