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):

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.

Analyzed the new data and sent the email to Ismael already.

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

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!
