WFCPOINT: Help

WFCPOINT - ROSAT Archival WFC EUV Data


Overview

The WFCPOINT database table contains the list of ROSAT-Wide Field Camera calibration (CAL), performance verification (PV), and AO phase observations.

For each observation listed in WFCPOINT, the target name, celestial co-ordinates, sequence number, PI name, and proposal title are given. The date of the observation, date that the data were distributed, and the date that the data will be released to the public are also given. The public release date is nominally 1 year and 14 days after the distribution date; however, because of some processing problems with a few datasets, the actual release date will be delayed from the given date.


Description

For a more complete description of the ROSAT spacecraft and its instruments -- the WFC and the XRT-PSPC and XRT-HRI -- see the ROSAT AO users guide.

Parameters

Name
The name of the target.

Alt_Name
The alternate name(s) of the target, if any were given in the ROSAT AO proposal.

ROR
The ROSAT observation request (ROR) sequence number.

_Public
Are data public? (YE or NO)

RA
The Right Ascension of the target.

Dec
The Declination of the target.

LII
The galactic longitude of the target, calculated from Right Ascension in J2000 coordinates.

BII
The galactic latitude of the target, calculated from the Declination in J2000 coordinates.

PI
The name of the Principal Investigator for the observation.

Title
