Subject: E2E 20050608 Shift-B Science Report.


The transition from Shift-A to Shift-B occurred during the FOV OF 
sub-test. One last 1D scan was made at focus position = -414 focus-steps. 
The analysis of the data is given on the 20050608-B analysis webpage. In 
summary, the scan profiles were consistent with those provided by 
Goodrich, although our alignment is off in some respect since the central 
maxima do not lie at an angle of p/y = (0,0). We made a conservative 
evaluation of the OF position to be at -280 um.

We then performed the Core PSF sub-tests with the Cu-L x-ray source for 
both BF and OF positions. Since time allowed, we repeated the measurements 
with the Al-K source. Analysis is given on the 20050608-B webpage. In 
summary, we saw shallow minima, indicating a broad field of focus. The 
contour maps of spot width over 2D pitch/yaw scans indicate an offset 
consistent with that indicated in the previous section.

There was some discussion between Austen, DeLuca, and Weber whether the 
results of these two sub-tests indicate that we should re-find the optical 
axis. Austen pointed out that the position suggested by today's data would 
cause the optical center to land further from the center of the CCD than 
our current pointing does.
