NEWS and Changes

2024-12-31 - Update of the OGLE-IV light curves with new data points collected until February 2024.
  • The observation epochs are now provided in the format of full Heliocentric Julian Days.
  • Re-reduced OGLE-IV photometry in some fields within the Galactic bulge.
  • Some stars have been reclassified as spotted variable stars and removed from the Collection.
See README files in the following On-line Data directories:
2023-11-12 - Candidates for Transiting Planets in OGLE-IV Galactic Bulge Fields from M. Mróz et al. 2023 (pdf)
  • new collection of Planetary Transits in BLG: OGLE-TR-1001 to 1099 (data from ftp)
2023-09-27 - Each star that is also a member of the OGLE-III Catalog of Variable Stars, got a link to its entry there.
That way, one can also examine OGLE-III photometry of each star, if available.
It is especially handy, for the stars that do not have regular OGLE-IV photometry.
