No astrometry
If there is insufficient astrometry in the current datafile or the
first file to calculate the offsets then the user is prompted for
them. The XOFFSET required is the number of pixels between the left
hand edge of the second data array and that of the first. If the second
array will be to the right of the image then XOFFSET will be positive.
Similarly YOFFSET is the distance between the bottom of the second
image and that of the first. If the second array will be above the
first then YOFFSET will be positive.
Note: In this case the program assumes that the input arrays have the
same intrinsic pixel size and the same orientation to North.
