Another question… just want to make sure it’s working correctly. The ancillary data are stored in nested directories first by year, then julian day. In one Julian day folder, there are 3 files- 1 AURAOMI_24h.hdf and 2 MET_NCEPR2_6h.hdf.bz2. Is the code going through all of these and matching the OLCI dates with the correct ancillary data date?
