Data types, location

types of file: nco = new correlator
fil = filters
sfr = sefram
sao = acousto-optical spectrometer

Your data are automatically transfered from the on-line computer toward the off-line one. Your raw data are stored in files, depending which back-ends you asked for:

                   type scan# uic
                   --------------
correlator spectra: nco023956.143
filters data      : fil023956.143
sefram data       : sfr023956.143
aos data          : sao023956.143

type of file: nco = new correlator
              fil = filters
              sfr = sefram
              sao = spectrometre acousto-optique

fil files are used for spectra calibration, or for continuum measurements.
nco and fil files are synchronized with the telescope tracking.
sfr files contain asynchronous total power measurements.
sao files contain asynchronous wide-band spectral measurements.

scan number: your observation number (6-figure number)
uic: telescope user id

Check in your data with lstdata:

$ cd /data2/guesti
$ lstdata -file nco -tail 10      ! restricted to nco files
$ lstdata -help                   ! help in french
