Final Observation Tapes (FOTs, the name being mutuated from the
EXOSAT mission)
are the way by which SAX observation data are made available to observers by
SAX/SDC .
A FOT consists in a series of files, containing scientific, housekeeping
and other kind of auxiliary data. One FOT contains the data of
all NFI instruments or of the two WFC.
As an example the following list of MECS files is present in a NFI FOT:
ephemeris_000000_00_0.dat ephemeris
attitude_000000_00_0.dat attitude data
m1dir002_00315_01_n.dat scientific data MECS 1

nnkkkkkk_ppppp_qq_r.dat name structure
nn = instrument
kkkkkk = packet type; dir002 = direct mode 002
eng = engeenering data
hkd = housekeeping data
ppppp = observing period
qq = observation
r = flag, n=normal, i=slew in, o=slew out

tapedirtape_000000_00_0.dat directory files. They contain the
meinstdirtape_000000_00_0.dat list of files in a tape, for each
meobsdirtape_000000_01_n.dat instrument and each observation
