Acronym to indicate the LWS Auto Analysis programme.
AAR
Auto Analysis Result. This is a generic name for the results of the
Auto Analysis program. For LWS it usually refers to the LSAN product
file, but it can also include the other product files generated by Auto
Analysis (LSNR, LGIF, LSCA, LIAC).
AOT
Astronomical Observation Template: The standard observing modes
for the ISO instruments.
ERD
Edited Raw Data. This is a generic name for the raw data files used as an
input to the Derive SPD program. In the LWS case it usually refers to the LGER,
LLER, LSER or LIER files.
EOHA
Edited Observation History File per AOT: This gives for every
AOT that was performed the timing and some information about
that AOT (see full description in the ISO Satellite Data Users Manual).
EOHI
Edited Observation History File per ICS: This gives for every
ICS that was sent to the satellite the timing and some information for
that ICS (see full description in the ISO Satellite Data Users Manual).
FP
Fabry Perot.
FPL
Long wavelength Fabry Perot.
FPS
Short wavelength Fabry Perot.
FWHM
Full Width Half Maximum.
ICS
Instrument Command Sequence: Command that will be translated by
the onboard software of the instrument to a sequence of actions. This is
the normal way to command the ISO instruments.
IDUM
Instrument Data Users Manual.
ISAP
ISO Spectrograph Analysis Package (?): software package
developed specifically for analysis of data obtained with the
two ISO spectrographs (LWS and SWS).
OCT
Observatory Command Template: template used to tranfer the
commands (instrument or other) to the satellite. This also includes
e.g. the pointing requests.
PV
Performance Verification: the initial phase of two months
of the ISO operations, when the instrument performance in orbit is
tested and characterized.
SCP
Spacecraft Commissioning Phase: The first three weeks of
ISO in orbit operations when all the systems of the satellite and
instruments are functionally tested.
SPD
Standard Processed Data: The result of the first stage of the
ISO data processing. This is one of the products that is sent to the
observers.
SPL
Acronym for LWS Derive SPD program.
TDATA
Transparent Data: Data that is passed from the commanding
(uplink) side of the ground station to the processing (downlink) side
of the ground station without passing through the satellite.
TDF
Telemetry Distribution File: The file format in which the data
is received from the satellite at the ground station.
UTK
Uniform Time Key: the time key that is used as a timekey
for all ISO data products (for details see the ISO Satellite Data
Users Manual).
