It was taking an average of 34.3 seconds build a fits file that is now dow to about 33.3 seconds. A zero overhead time would be about 32.9seconds (this time includes only camera integration time, camera read time and lyot filter relaxation time). The changed made to do this were: To optimize he way we get camera temps, the 4 measurements were done serially with 4 function calls (and need to be done while we aren't taking data. The calls are now done in parallel between the two cameras in one function that collects all 4 values. The LCVR ini files are now read once when the UCoMP controller is started instead of once per recipe. (These ini files change every few months when Steve changes offsets.). Moved a check of the CAL optics positions to be a little earlier in the recipe code, to get it out of the fast critical path to triggering camera reads. This was a very small change I don't think it actually improved performance. ___end___ UCoMP COMMENT BY Observer: Sat Apr 16 23:42:27 GMT 2022 Fixed a bug in the ucomp mech-controller that wouldn't let the O1 home. Homing now seems to be working from the controller, and should be run from that location if/when it appears the O1 is not behaving well. While we call it homing, it technically resets the controller and then finds the home switch so it is alos like rebooting the mDrive motor. ___end___ ONSITE STAFF: berkey
