Scientific paper

Repeatability tests were performed on a PDS1010G microdensitometer. From these measurements, extended up to 11 hr, significant drift of coordinates reaching several microns and occasional discrete 1 micron glitches are found in accordance with similar results from other PDS granite systems. With the present system configuration therefore precise astrometric measurements cannot be performed without substantial instrumental modifications.
