Iterative maximum likelihood fit of infrared detectors ramps

This package contains the code described in Gennaro and Khandrika (2021), see https://ui.adsabs.harvard.edu/abs/2021wfc..rept...11G/abstract .

The code is used to perform the up the ramp fit of infrared detector ramps. It can be applied to ramps with arbitrary number of groups, averaged frames per group and skipped frames.

Content

The ramp_utils package

The main routines for simulating and fitting ramps are contained in the ramp_utils package.

• ramp.py defines the RampTimeSeq class and RampMeasurement class, than can be used together to created simulated ramps
• fitter.py defines the IterativeFitter class which is the workhorse code for fitting the ramps and obtaining an estimate of the true incident flux

Example notebooks in Test_notebooks

The Test_notebooks folder contains a series of examples to help the user familiarize with the code and its functionalities
