#### Description

Check the MTMount tracking trajectory data. Russell did the following tests at 11/23:

1. Track a ramp from az=-40.0, el=30.0 to az=-39.0, el=41.0 deg at speed az=0.05, el=0.025 deg/sec; this will take 440.00 seconds

2. Track a ramp from az=-40.0, el=30.0 to az=-39.0, el=31.0 deg at speed az=0.05, el=0.025 deg/sec; this will take 40.00 seconds

The timestamp is 1669244241.788 (the only timestamp I could find in the slack channel):

Please help to review the following notebook for this effort (I have no plan to merge this feature branch to develop branch):

https://github.com/lsst-ts/ts_notebooks/blob/feature/analysize/procedures/MT/rotator/trajectory_mtmount.ipynb

I have the question after checking the data in EFD. I thought the tracking speeds should be 0.05 deg/sec and 0.025 deg/sec based on your slack message. But the data showed it should be 0.1 deg/sec.

Do you have any idea what should be the speeds you issued at 11/23 night?

Thanks!

The speeds should be as listed in the slack channel. The timestamp in a message at 7:57 was 1669244241.788 (and it may have taken me a few seconds or a minute to paste it) and the two ramps were at 8:04 and 8:12 so I would expect the ramps to start at about 1669244241.788 + 12 minutes and 1669244241.788 + 15 minutes. It might be worth checking for the MTMount entering tracking mode. Next time I can provide proper timestamps.
