INES spectral files are transformed into MIDAS ``.tbl'' files with the command "INDISK/FITS''. These files have four columns containing Wavelength, Flux, Sigma and Quality flag:
Midas 002> indisk/fits SWP25774LL.FITS SWP25774LL
FITS file SWP25774LL.FITS converted to SWP25774LL.tbl
Midas 003> show/tab SWP25774LL

The bi-dimensional SILO images are also written in FITS format and can be accessed with the same command "INDISK/FITS":
Midas 005> indisk/fits SWP43250.SILO SWP43250 FITS SWP43250.SILO converted Midas 006> $ls *.bdf SWP43250.bdf x__x0001a.bdf
This command creates two files, one holding the SILO image itself and other (x__x0001a.bdf) containing the bi-dimensional quality-flag image. It is recommended to rename this latter image since it might be overwritten by successive calls to INDISK/FITS.
Note also that FITS image files can be accessed directly in MIDAS without converting into bdf files:
Midas 007> read/desc SWP43250.SILO frame: SWP43250.SILO (data = R4, format = FITS) NAXIS: 2 NPIX: 640 80 START: 1050.0000000000 1.0000000000000 STEP: 1.6763900000000 1.0000000000000 IDENT: CUNIT: FN WAVELENGTH SCAN LHCUTS: 0.0000000E+00 0.0000000E+00 -77.30000 239.7000
