All spacecraft and instrument data needed to process observational
data from the Raw Data level onwards are archived. [Spacecraft
pointing and velocity data are examples.]
Mission-planning data
All data needed for the planning of observations, including proposal data
abstracts, are archived. [PH reports, the Mission
Data Base, the ISO Log and CAL-U files are examples.]
Diagnostic data
All spacecraft and instrument data needed for diagnostic and
trend-analysis purposes are archived. [QLA reports and data needed to
correlate observational data with orbital position are examples.]
Space weather reports, obtained from external sources, are archived.
There are many observational details and associated files connected to each individual observation in the archive. For example, observation identifiers of all concatenated observations or raster parameters used by the spacecraft when making a celestial map are given in a short summary. Many associated files, which were mainly used for planning of observations and uplink, are also available. Most of them are only for expert usage. The following give a short summary of associated files:
POF: | Planned Observation File |
ICS: | Instrument Command Sequence |
CUS4_ICPT: | Calibration Uplink System Instrument Calibration Parameter File |
CUS4_ICS: | Calibration Uplink System Instrument Command Sequence |
CUS4_IDSDB: | Calibration Uplink System Instrument Default Setting Data Base |
CUS4_VERBS: | Calibration Uplink System Verbs |
RRP: | Real time Revolution Report |
ISR: | Instrument Station Report |
COIF: | Calibration Observation Input File |
COB: | Calibration Observation Batch |
CO_PARAM: | Calibration Observation Parameters |
CO_LIST: | Calibration Observation List |
TIMELINE FILE: | Calibration Observation scheduling instructions (PHT specific) |
IPF: | Output file of the program PHTAOT (PHT specific) |
Additionally, the proposals abstracts are available for most of the observations. All these products can help to understand and/or interpret specific aspects of a measurement.
All versions of derived calibration data which have been used to process the observational data from the Raw Data level onwards are archived. [Cal-G files are an example].
All data needed to reconstruct the chronology of the mission are archived.
All documentation existing in electronic or widely-distributed hard-copy form is archived.
A number of software packages are available to the community to reduce and analyse ISO data. These include: ISOCAM Interactive Analysis (CIA); ISOPHOT Interactive Analysis (PIA); Observers' SWS Interactive Analysis (OSIA); LWS Interactive Analysis (LIA); and ISO Spectroscopic Analysis Package (ISAP). They all can be obtained through the ISO Data Center web pages at:
