GLSFit.pro

GLS routines to calculate linear fit

analyze_dark_ramp.pro

Wrapper to correct NIRCam dark ramps for 1/f noise and derive dark map and RON

correct_evenodd_ramp.pro

This function corrects for the even-odd effect in full frame NIRCam files

corrector.pro

This file contains the procedures to perform the reference pixel correction of NIRCam data according to the report by M.

covar2ellipse.pro

NAME: MPCHILIM

density.pro

This procedure shows the density of points in an x-y plot.

find_files.pro

This function finds the list of fits files to be processed, according to specified keys; all must be in a given directory

generate_ramp.pro

get_telemetry.pro

A little script to read the temperatures from the telemetry file, use as an example

linearize_mr.pro

opencloseps.pro

optimal_smooth_fft.pro

This file contains the procedures to perform optimal filtering of the vertical reference pixel to reduce 1/f noise (horizontal stripes), based on the Kosarev & Pantos algorithm

ramp_basiclinfit.pro

This function performs a basic linear fit, returns intercept and slope for each pixel

ramp_common_level.pro

This function matches the four sectors of each frame to a common level.

ramp_fixsectors.pro

This function corrects for the amplifier reset of NIRCam ASICs by matching the top/bottom reference pixes of adjacent groups

ramp_getron.pro

This procedure creates a 2-D RON map by subtracting from a dark current ramp the linear fit, and estimating the residuals stdev for each pixel

ramp_optimal_filter.pro

This function performs an optimal filtering of the vertical reference pixel to reduce 1/f noise (horizontal stripes)

ramp_plot_4histo.pro

This function

ramp_plotbasiclinfit.pro

This procedure plots the histograms of the two linear fit parameters, returning also the results of the gaussian fit.

read_one_ramp.pro

This procedure reads a single fits file in multiaccum format

run_glsfit.pro

GLS routines to calculate linear fit

set_detector_params.pro

This function sets the main detector parameters to be transmitted to other routines through common blocks

temp_convert.pro

Convert the temperature in the telemetry file (or fits headers) from ADUs to decrees
