The
WFPC2 mosaic covers an area of 5 arcmin2 and consists of a
34'' x 34'' PC1 CCD image and three WF CCD images each 80'' on a side.
The image here is a greyscale
representation of the median of four V band HST WFPC2
images (each with an exposure time of 8 s) of the central region of
M15.
The gaps shown in the figure do not accurately represent the slight rotations
and actual gaps between the fields of view of adjacent CCDs. The cluster
center is located in the PC1 CCD. The scale and orientation of the image are
indicated in the upper right.
