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)
