In the process a spring that puts tension on the synchro unwound. We are not sure if we have lost position information on the barrel. Eric is trying some different positions on the barrel to get our bearings straight.

Several itrrations of synchro rotation until 15 tilt opal in scan aligned itself with the FRAMS grid. Looks like a normal calibration. Think barrel is aligned correctly.

Now running mask scan with opal in to get info on scaling factor. Hairlines not noticable in upper detector and that is why we used the mask. We have taking the mask out and have started taking data at 2300. Hair lines still in and now we see them with the upper detector, furthermore the up and down alignment of the two detectors appear right on. This is confirmed by the P+S signal showing three hair lines of about 1 pixel width each. The hairline valleys coienced between P and S by better than one pixel. Width of hairlines narrowed from 5 to 4 pixels. Note that the hairlines appear narrower when using the opal.

First put in mask and marked ocillascope with location and amplitude of signals from mask. Cleaned mirror with air and replaced. Found no signals on scope. Very, very subtle changes in tightening the mirror holder screws brought the signals back into alignment with marks on the scope. Removed mask and started taking data again in poor sky about 2430.
