TITLE: GCN GRB OBSERVATION REPORT
NUMBER: 4627
SUBJECT: Erratum: SDSS pre-burst observations of GRB fields
DATE: 06/02/01 16:08:43 GMT
FROM: Richard J. Cool at U.of AZ/Steward Obs <rcool at as.arizona.edu>
Richard J. Cool (University of Arizona) reports:
Based upon feedback from users of our online releases of SDSS photometry
and astrometry of GRB fields, we have discovered an error in several past
releases. In preparing the releases, we inadvertently neglected to remove
duplicate listings of several objects from the online catalogs. Several
of the secondary observations of the objects included are of lower
photometric quality than the primary observation and thus photometric
zeropoints derived with them may shift slightly. We removed all duplicate
observations from the online catalogs for past
bursts located at http://mizar.as.arizona.edu/grb/public/.
We apologize for any inconvenience.
