Finding charts are PNG images. The names of the files are in the form: 
ID.png. The finding charts are 60"x60" subframes of the I-band reference 
frames centered on the stars. White cross marks the star. North is to 
the right and East is up.


Any presentation of the scientific analysis or usage of the data from
the OGLE Atlas of Classical Novae should include the appropriate
reference(s) to OGLE paper(s).
