Description

bspline.py

• johntfoster's python implementation of Bspline basis function via Cox - de Boor algorithm. Includes memoization for rapid recalculations.

calibration_script.py

• reduces calibration frames to produce masterbias, masterdark, mastertrace_twi, masterarc frames, as well as distortion and fiber model files.

call_cure.py

• python interface with many CURE functions

examine_darks.py

• In progress script for looking at dark frames

gain_readnoise.py

• Measure gain and readnoise from bias/flat frames. Can be fiber flats or full flats.

ifu_normalization

• Script to normalizes IFU to IFU through fiberextract and averaging the twighlight frames as a function of wavelength. Can apply normalization to FE frames.

science_scripty.py

• Science reducitons to be run after calibraiton_script.py

utils.py

• Useful mathematical functions including biweight_location (with axis argument)
