Abstract:
Photovisual and photographic magnitudes of more than 400 stars in the
globular cluster M22 have been measured. The resulting color-magnitude
diagram extends to slightly fainter than the RR Lyurae domain and is
generally similar to those for other globular clusters, in particular
most resembling the diagram for M13
Description:
Positions have been derived for the stars in the finding chart at CDS
in June 2016.

Note (1): the star number is of the form SNNN, where S is the sector number
from 1 to 4 (corresponding to NE, NW, SW and SE respectively), and NNN
the number written on the chart.
Note (2): position determined at CDS from the chart, with the origin of the
position: M=2MASS (II/246), U=UCAC4 (I/322), and * for other (see Notes).
Note (3): notes added at CDS. This note provides other Simbad-understandable
names for the star, and/or notes about possible confusions.
