Sure, I can help with that. If you'd like to write it yourself, the specifications are pretty simple:
1) The function takes a single input, the filename of the image file that you're loading the header for.
2) The function returns a single dictionary, where the keys are the header items (things like 'Date', 'Beamstop Counts', 'Flux', etc) and the values are the value of those items in the header file. The dictionary keys should be strings, the dictionary values can be any type, but if you're going to use them for normalization they should be something that python can cast as a float.
3) Add your new function as a header type in the all_header_types dictionary on line 915 of the SASFileIO.py file.
You can see examples of these loading functions in the SASFileIO.py file starting around line 418.
Once you've written it, send it to me and I can include it in releases of RAW going forward.
Alternatively, if you send me an example dataset with images and associated header files, and an explanation of the file format, so I know what to load, I can write the load function for you when I have time, and include it in the subsequently released version of RAW.
All the best.
