Catalogs created by Glenn Gombert

Glenn Gombert has been using his Mark III triplet in Ohio for many months now. He has compiled large catalogs of stars which his system has detected repeatedly.

• Glenn Gombert's "master" photometry file, based on >= 26 nights of data from the Dayton triplet (updated Mar 14, 1998). It contains mean V, I measurements, positions, and cross-IDs into the Hubble Guide Star Catalog for about 80,000 stars. Glenn used Arne Henden's routines to collate and transform the magnitudes to the Johnson-Cousins V,I system. Since the ASCII file is 6.1 Meg in size, you may want the smaller, 1.8-Meg zip'ed version.

• "Master" photometry file covering the period July 1997 to May 1998. Contains positions and average magnitudes for about 93,000 stars, but does not have cross-IDs into the GSC.
  The ASCII version is about 6.8 Meg,
  The zip'ed version about 2 Meg.

• "Diffcal" data file for the period July 1997 to May 1998. Contains positions and magnitudes for each observation of each star -- so this is the file needed to make light curves.
  The zip'ed version about 10 Meg.
