FUSELOG - Far Ultraviolet Explorer (FUSE) Observation Log
FUSE (Far Ultraviolet Spectroscopic Explorer) Observations FUSE Science Team <Johns Hopkins University (1999-2007)>
FUSE Preview Page: This contains the FUSE `Preview' spectra of the object and other information FUSE Search Results Page: This is the MAST results page which is generated by a search in the FUSE Archive using the specified ObsID (the first 8 characters of the parameter Data_ID in the MAST FUSE Archive) FUSE Proposal Information: This contains the abstract of the proposal for which the observation was made, a list of papers which have referenced these data, and a list of all observations made for this program
A unique dataset identifier, the first 4 digits of which contain the proposal identifier.
The name of the target of the observation.
The Right Ascension of the telescope pointing in the selected equinox. This was given in J2000 decimal degrees to a precision of up to 0.0001 degrees in the original table.
The Declination of the telescope pointing in the selected equinox. This was given in J2000 decimal degrees to a precision of up to 0.0001 degrees in the original table.
The Galactic Longitude of the telescope pointing.
The Galactic Latitude of the telescope pointing.
The observation date and time.
The exposure time of the observation, in seconds.
The aperture mode used in the observation. The following values are possible:
LWRS (30"x30"; 100% throughput) MDRS (4"x20"; 98% throughput) HIRS (1.25"x20"; 85% throughput) PINH (Pin hole - hasn't been used as of 9/24/2002) RFPT Used either for instrumental test programs, or when long background observations are made. The latter are tagged with a target name, but since the target is at the reference point, its light is not entering the spectrograph through one of the science apertures.
The operating mode used in the observation. The following values are possible:
TTAG = time information of events are accessible HIST = histogram mode
The number of exposures which make up the observation.
The FUSE object classification, a numerical scheme which is close but not identical to that used by the IUE Project:

A flag which is set to 'Y' if the dataset has been released to the public.
The last name of the Principal Investigator of the proposal. There are a number of observations (those having with obsid values of 'S405*', 'S601*', 'Z90*', and 'Z91*') which the FUSE Project calls 'FUSE Observatory Programs' and appear to have no Principal Investigator per se; the HEASARC has given these observations pi_fname values of 'FUSE' and pi_lname values of 'Observatory'.
The first name of the Principal Investigator of the proposal. Notice that these are not necessarily consistent between different proposals of the same PI, so that, e.g., a PI with the first name 'Theodore' may also have proposals with his pi_fname = 'Ted' or 'T.' Therefore, this parameter is not a good parameter to use in a search, and the HEASARC recommends using the pi_lname parameter for this purpose.
The institution of the Principal Investigator of the proposal.
The title of the proposal from which this observation was derived.
The HEASARC Browse object classification, based on an approximate translation from the fuse_class parameter. The latter parameter should be regarded as the more definitive one.
