Finding charts are gzipped Postscript images. The names of the files are
in the form: OGLE-BLG-DSCT-NNNNN.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 delta Scuti-type stars should include the appropriate
reference(s) to OGLE paper(s).


Updates:

2022-08-20  28 delta Scuti stars from the Gaia DR3 catalog added
            (from OGLE-BLG-DSCT-16832 to OGLE-BLG-DSCT-16859)

2022-12-15  24 additional delta Scuti stars confirmed spectroscopically
            (from OGLE-BLG-DSCT-16860 to OGLE-BLG-DSCT-16884)
