Description:
  Photometric measurements in V and I of more than 5x10^3^ stars (and in U, 
  V, and I of >~1500 stars) are used to construct color-magnitude diagrams
  in the central 1' of M15. Fourteen blue straggler candidates are
  identified in the inner 20".

Note (1): Coordinates are arcsec offsets relative to AC 211 = ID 653.
           ID 653 is at RA(2000)= 21:29:58.26 Dec(2000)=12:10:02.90
Note (2): a - the star is located outside the area covered by the U image.
          b - the star is not detected in U, though the area was covered.
