Matt is asking for changing the format of the IDF xml to use "roc" number for detector banks.
In consultation with @AndreiSavici, it may be a good idea to have the output of calibration in a simple text file format like this file, which was used to generate the earlier SEQ IDF file using this script
The calibration was previously saved to xml file and used in mantid: https://github.com/mantidproject/mantid/blob/f1765c1dda3c809cb2e3d38895f29c0d04ecf416/instrument/SEQUOIA_Definition.xml
