Since a ROSAT PSPC image is 15360
15360, the above command only
displays a small part. To see the whole image, compress this by a factor
of 30 to
512
512. The factor of 30 compression is called a ``blocking
factor'' (ie. block=30). Blocking factors work only with QPOE (*.qp)
files and not with image (*.imh) files.

Note: the quotes are necessary when this modified file name is used in the command line mode.
