Subject: E2E 20050609 Shift-A Science Report.

The analysis for tadaya centered around two main issues. Fisrt, an attmept
to determine the offset between the VLI and X-ray optical axis was made.
Several issues concerning this measurement have been resolved, and the
calculations should be complete shortly. 

The PSF wing measurements at the best focus position were also started. We
have taken nearly 100 images for this analysis. These include 75 8x8
summed 64 second exposure images, dark images, 10 full resolution 16
second images and a number of additonal images after the end of shift A.
We have made plots of the integrated counts outside a radius of 4 and 8
pixels and will have plots of these results in the morning.

We also started the filter tests, beginning with the Al filter. Subtantial
counts were observed in the images using this filter and the Al source.
These tests were to continue following the completion of additional images
requested for PSF wing measurements.
