*display, xdisplay* -- Displaying an image in detector coordinates

The following command will display a .qp file in the original detector coordinates. In this case a ROSAT PSPC image is used so it is also blocked to a reasonable size:

  xp> xdisplay ``xdata$rp110590.qp[block=30, key=(detx, dety)]''

Alternatively, higher resolution can be obtained with the following command which displays the bottom left hand quadrant of a $1024\times 1024$ array:

  xp> xdisplay ``xdata$rp110590.qp[block=15, key=(detx, dety)] [1:512,1:512]''
