Check the last 20 to 40 images on the VIPS, to see if artifacts or other
image quality problems occur.
4.1 Test Cycles

4.2 Exposure of a Flatfield
Expose an image plate of every format and evaluate all the images on the

homogenous field or stripes criteria. The hard disk of the digitizer provides two
flat field samples for quality comparison.
Repeat this procedure for all formats on site!
