irispreppy 3.1.3

For radiometric calibration and point spread function deconvolution of IRIS spsetcrograph data

irispreppy

For radiometrically calibrating and PSF deconvolving IRIS data.

To install simply run pip install irispreppy.

I dislike how I need to own proprietary software (IDL) just to simply prepare my data. I use Python for my analysis, why can't I radiometrically calibrate and deconvolve with it? This has been a passion project of mine during my PhD (and beyond). The radiometric calibration keeps itself up to date with the response files by checking https://hesperia.gsfc.nasa.gov/ssw/iris/response/ every time it is run. If it finds new files, it downloads them before continuing.

These scripts should be general purpose and "just work". No janky hacks are present.

tl;dr usage

irispreppy takes a single HDU object. To calibrate and deconvolve,

from astropy.io import fits
import irispreppy as ip

raw=fits.open("iris_raster.fits") #Raw data
rc=ip.radiometric_calibrate(raw)  #Radiometrically calibrated
rc_d=ip.deconvolve(rc)            #Radiometrically calibrated and deconvolved

To calibrate and deconvolve, and save,

from astropy.io import fits
import irispreppy as ip

raw=fits.open("iris_raster.fits")   #Raw data
ip.calibrate_and_save(raw)          #Radiometrically calibrated
rc=fits.open("iris_raster_rc.fits") #Radiometrically calibrated data
ip.deconvolve_and_save(rc)	        #Radiometrically calibrated and deconvolved
