For radiometrically calibrating and PSF deconvolving IRIS data.

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. 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.

This remains untested on Windows and Mac. However, I expect it to work on UNIX-like OSes.

Comments

Combination of HDU and `save=True` arguments to radiometric calibration

If an HDU is passed instead of a str containing a path, the code will attempt fitsHdu[-5:] + '_rc.fits'. Which is an issue that should be checked somewhere. This is likely an issue if a list is passed too.

Versioning and Install issues

The current pip version tries to get beautiful soup through bs4 (which fails on most python), and the current tree goes for beatifulsoup4 (typo). Try and sort the astropy requirements too? Is there an issue with >v4.2.0 ?

Code will always warn that you are offline

https://hesperia.gsfc.nasa.gov/ssw/iris/response is now a 404.

NASA have removed the public facing SSW page due to "hacking" after an attack took the site offline. I will have to find an alternate source for these files or attempt to update them manually.

Calibration of Files Created after 2022-01-01 Have Significantly Less Flux

For the time being, it is recommended to use files predating 2022. This was found when comparing h2r intensities over time. On 2022-01-01 there is a discontinuity where these drop. This drop is not present in uncalibrated data.
