Finding charts are gzipped Postscript images. 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)
