The directory structure is as follows: README - this file ident.dat - identification of stars Miras.dat - parameters of Mira stars phot_ogle2/I/ - I-band OGLE-II photometry of individual stars (1997-2000) phot_ogle2/V/ - V-band OGLE-II photometry of individual stars (1997-2000) phot_ogle2.tar.gz - gzipped phot_ogle2/ directory phot_ogle3/I/ - I-band OGLE-III photometry of individual stars (2001-2009) phot_ogle3/V/ - V-band OGLE-III photometry of individual stars (2001-2009) phot_ogle3.tar.gz - gzipped phot_ogle3/ directory phot_ogle4/I/ - I-band OGLE-IV photometry of individual stars (2010-2020) phot_ogle4/V/ - V-band OGLE-IV photometry of individual stars (2010-2020) phot_ogle4.tar.gz - gzipped phot_ogle4/ directory fcharts/ - finding charts of individual stars paper.pdf - PDF version of the paper Iwanek et al.

The names of the files are in the form: OGLE-GD-LPV-NNNNNN.ps.gz. The finding charts are 60"x60" subframes of the I-band reference frames centered on the star. White cross marks the star. North is up and East to the left. Any presentation of the scientific analysis or usage of the data from the collection of Mira stars should include the appropriate reference(s) to OGLE paper(s).
