B. List of acronyms

AAL

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).
