keyword=abandon temporarily optics runs
After 6 hours of effort, Ed and company still cannot get the readout for the HRS-L collimator to work. Bottom line: we have spent a lot of time with this and it is still not possible to position the sieve slit so that it is reliably known to be in the correct position. Therefore, I made the decision to abandon for now the negative polarity optics runs and to return to positive polarity with the open collimator (whose position can be verified visually). Eventually, we will have to get this problem fixed, since we will have to do sieve slit optics runs. However, we need not do this right now.
