Since a ROSAT PSPC image is 1536015360, the above command only displays a small part. To see the whole image, compress this by a factor of 30 to 512512. 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.
