ChroTel missing FILENAME in headers
Problem
For some files from ChroTel, headers do not contain the default FILENAME
field in favor of a FITSFILE
field.
Workarounds
Importers can handle this
File records in
chrotel_l1_data.files
collection are updated using the `filename` attribute of the GridFS record. vlue was set onmetadata.header.FILENAME
ChroTel headers and the metadata.header.FILENAME
field do not match!
