-Control system throwing error when crosses next magna sensor - error is too large- don't know if something  has gradually changed over th year and need to open up limit for that error or wether there is hardware problem happens when telescope is tracking or slewing azimuth direction onyl- arc second size error +Bill provided some additional information about the telescope error described above. The telescope control system is throwing an error as it is slewing in the azimuth direction when it crosses the next magna sensor. It is unclear whether something has gradually changed over the years such that we need to open up the limit for that error (currently it is deemed to be too large, which is causing the issue), or whether there is some kind of hardware problem. This is still under investigation. It happens when the telescope is tracking or slewing, but only in the azimuth direction. The resulting pointing error is arcseconds in size.

Sarah reported that she has a finalized quote from one vendor. The grism design turns out to be a little complicated, but also, costs have gone up, so these are more expensive than we expected (ballpark $20k apiece). Therefore, we need to explore potential funding sources. Nancy will amass all previous emails with grism requests and send to UC reps to query users about whether there is broad interest in particular grism.
