ASCAMASTER - ASCA Master Catalog
Notice that, if one or more of the date parameters are empty for a given observation, this means that that those particular processes have not occurred: e.g., if observed_date is empty, this means that the planned observation was not observed.
The sequence number of the observation.
The last name of the Principal Investigator.
The first name of the Principal Investigator.
Principal Investigator number.
The ASCA proposal number corresponding to this target.
The AO number in which this target was accepted, or 0 for PV (performance verification) phase target.
The subject category of this target as specified by the PI:
STARS CATACLYSMIC VARIABLES X-RAY BINARIES SUPERNOVA REMNANTS AND GALACTIC DIFFUSE EMISSION NORMAL GALAXIES ACTIVE GALACTIC NUCLEI CLUSTERS OF GALAXIES AND SUPERCLUSTERS COSMIC XR-RAY BACKGROUND, DEEP SURVEYS, AND OTHERS
The name of the target.
The number of this target in the original proposal.
The Right Ascension of the target.
The Declination of the target.
Time awarded for observation in ksec.
Priority, where 1 means highest and 3 means lowest; targets accepted at priority 3 are not guranteed to be observed.
The start time of an observation. If an observation has been scheduled but not observed, this parameter contains the scheduled time for an observation. Once an observation has been observed, this parameter contains the actual observed time.
The total elapsed time (end time minus start time) of completed observations, including Earth blocks and SAA passages, in seconds.
Status of an observation indicated by : 'Accepted', 'Scheduled (long term)', 'Scheduled (short term)', 'Processed', 'Archived'.
The date on which the observation is scheduled to occur.
Once an observation has been 'observed', Observed_date contains the date on which the observation was made.
The date that the data for this observation were processed by the ASCA Data Facility.
The date observation was first distributed, in seconds since 1980, to the primary PIs. NOTE: The distribution dates may not be completely accurate since they are sent to us from Japan.
The date that the data for this observation were made public. The following are the rules that govern how long ASCA data is proprietary (i.e., available only to the original proposal team) before it becomes public:
The following proprietary periods apply to the ASCA data:
* US and joint US/Japan data will be public 1 year + 2 weeks from their dispatch to the PI. * Japanese and joint Japan/US data (with a Japanese PI) will be public 18 months + 2 weeks from their dispatch to the PI. * Calibration data enters the public domain as soon as they are processed.
Process_level The processing revision number. Numbers that :
start with '5' are rev1 start with '6' are rev1+ start with '7' will be rev2
BROWSE classification type.
The last name of Co-Principal Investigator.
The total GIS exposure time in seconds which standard processing has flagged as good.
The total SIS exposure time in seconds which standard processing has flagged as good.
The end time of the observation in seconds since 1980.
The Galactic Longitude of the target.
The Galactic Latitude of the target.
