(see my notebook)<br /> MIRC pieces need to move down a few mm (3 mm?)<br /> <br /> 3. New MIRC control system. <br /> a. upgrade devel account to sudoer list, copies files from /root/MIRC<br /> b. run % sudo RTscheduler 60000<br /> % spooler<br /> These two procedures are actually under /usr/local/bin/ as we found out later, not the ones<br /> inside the folder.<br /> c. open IRCam gui, and follow the normal observation procedure: update DAQ parameters, config camera, ...<br /> d. open fiberexplorer gui, and following the normal observation procedure: load camera conf, fiber mapping...<br /> All the above steps are working well, I didn&#039;t spot any error.<br /> <br /> Then I start to save some data, and find two errors.<br /> 1. Frame counterror: receive only XXX out of 1500 frames.<br /> 2. 4Header read error<br /> <br /> For the first error, I think we have seen that before. But it is happening more frequently, I saved 64 files, and it happened<br /> 5 times.<br /> For the second error, I have never seen that before, is this the header problem you mentioned before? IT happened twice<br /> during saving 64 files.<br /> <br /> I looked into the saved files. Because we are not on a real target, I am not sure if the header is right. But it looks normal, nothing wired.</div>
