Description:
File table1 contains equatorial coordinates for 36 newly identified
variables from the central field of the globular cluster M22.
File table2 contains basic photometric data for SX Phe stars
reported in the paper.
File table3 contains magnitudes and colors for selected sample of
new variables.
Files table4-39 contain V-band time-series photometry for 36 newly
identified variables from the central field of the globular cluster
M22.
Individual finding charts for new variables are in fig directory;
each chart is 33arcsec on a side with north up and east to the left.
