A1849 lbw mapping with wapp in preparation for alfa
jan04
Intro:
Example of polB
jumping during a scan. This was being caused by the dewar temp monitoring
circuitry for the 70K stage.
A look at what
mapping has been done at ao 01jan01 thru a1jan04 with interim correlator
at lband.
-
Top : all mapping scans taken in this time period. The points show the
start of each strip.
-
Bottom. The mapped points for the region around 23:30:00, 8:00:00 The green
dots are the centers of complete maps.

A description
of each of the 9 completed maps for the bottom figure. These maps
have ra Offset of about 10 amin and dec offsets of 10Amin. So they cover
about 20Amin by 20Amins (except the 6th map which is 30 by 26). The integrations
are 30 seconds per point and a drive rate of .07 amin/sec.
