Surface differences, 15 June 2002

On 15 June between 17h46 and 16 June 1h30, six 80 GHz maps have been made.
The first five maps were on a standard 40 arcsec raster, the last map was on a tilted 20 arcsec raster.
In between some of the maps some panels were moved for adjuster tests.
The plots below show the difference of the maps with respect to map 5 which was started at 22h15
(see the map at the bottom of this page).
It is seen that the differences decrease in size for the first three maps to about +/- 10 micron,
but increase again to almost 40 micron (in one corner) for the last map.
