20060831 report
RxA pointing
Pointing was obtained w/RxA during the night of UT 31 Aug.
32 data were logged; a few at the end were all on crl618 during
other tests, although they covered a non-trivial range of (az,el) space
and so I have left them in the reduction for now. Two early entries
from this series on crl618 were removed for other reasons, as were
one of the logged entries for w3(oh) and the troublesome observation
of PV Cep. The remaining 28 data were reduced using
TPOINT
and a pointing model derived which should have a performance
in (dS,dZ) of (3.2",2.3"). Removing also the several pointings reported
in ompobslog as being of suspect nature left 21 data, and a new fit
generated a model with an expected (dS,dZ) of (2.8",2.3").
Given the early state of the recovery of the telescope, either of
thse results seems reasonably good. The N=28 model has been installed
(16:30 HST 31 Aug 2006) because of its fuller (az,el) coverage.
