Recent Observations

The ACA Problem is in the specified handling of guide star positional errors.
This issue in not significant to the final product and so is being worked at low priority.

It looks to me as though the HKABIASLEAKI measurement is clipping at 1.0, although the trend would suggest that it is frequently going
higher. is this a problem with the programmed constants on our A/D converters or in the EPHIN itself (i don't know where the A/D
is)? there may be some of this going on in the other measurements too, given the fairly marked upward trends and increasing variability of many of these -Mark Freeman Sept. 7, 2001
