I was able to read the upper sideband into MIR/IDL, on Neptune. � The
readdata command took 4 hours to complete, and over 100 Gbytes of RAM
was grabbed. � �Unfortunately, I could not do much with the data once it

Do you have the error messages ? Maybe some data types need to be changed to accommodate the large number of scans in MIR.
