The directory structure is as follows: README - this file ident.dat - identification of stars acepF.dat - parameters of fundamental-mode anomalous Cepheids acep1O.dat - parameters of first-overtone anomalous Cepheids phot/I/ - I-band photometry of individual objects phot/V/ - V-band photometry of individual objects phot.tar.gz - gzipped phot/ directory fcharts/ - finding charts of individual objects remarks.txt - remarks on selected objects pap.pdf - PDF version of the paper Soszynski et al. (2015), Acta Astron. 65, 233, (arXiv:1508.00907) describing the catalog.

The names of the files are in the form: ID.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 catalog of anomalous Cepheids in the Magellanic Clouds should include the appropriate reference(s) to OGLE paper(s). Updates: 2017-06-30 The collection extended with Cepheids from OGLE-LMC-ACEP-144 to OGLE-LMC-ACEP-145 detected in the OGLE-IV auxiliary photometric databases. Light curves of other objects supplemented with new observations. For details see: Soszynski et al. (2017), Acta Astron. 67, 103 (arXiv:1706.09452). 2018-07-12 Corrected erroneous calibration of the I-band photometry for 6 objects. 2019-02-07 OGLE-LMC-ACEP-005 reclassified as a first-overtone type II Cepheid (OGLE-LMC-T2CEP-290). Removed from the list of anomalous Cepheids. For details see Soszynski et al. (2019). 2019-07-04 The collection extended with Cepheids from OGLE-LMC-ACEP-146 to OGLE-LMC-ACEP-149 detected in the OGLE-IV outer fields. For details see: Soszynski et al. (2019), Acta Astron. 69, 87 (arXiv:1907.02073). 2022-08-20 1 additional anomalous Cepheid from the Gaia DR3 catalog (OGLE-LMC-ACEP-150) 2023-09-25 1 additional anomalous Cepheid from the Gaia DR3 catalog (OGLE-LMC-ACEP-151)
