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 Milky Way should include the
appropriate reference(s) to OGLE paper(s).

 
Updates:

2020-07-16  65 additional anomalous Cepheids (from OGLE-GAL-ACEP-056 to   
            OGLE-GAL-ACEP-120; Soszynski et al. 2020, Acta Astron. 70, 101)
