Flexure tests of the Cassegrain spectrograph Flexure tests of the Cassegrain spectrograph Flexure tests of the Cass spectrograph have been conducted on November 17, 2000. We didn't want to shake things up. Maybe that would be something else to test for. I am sure can do the same.
Results come out a bit different.
The new shifts have very similar HA-dependence as those in 1994. In conclusion, there is no obvious need to change anything in the Cass spectro counterweight system. The results will serve as a reference when the new, heavier CCD will be installed.
