The 16 new feeds are: 1c,1e,1g,1h,1k,2a,2b,2e,2h,2j,2m,3c,3d,3l,4j,5b

• A description of how the feeds are tested each week, see Feed Testing
• Feed control commands document
• Feed control measurements during commissioning
• Notes on resetting a turbo pump on 2j

The sensors on the dishes and on the feeds are now periodically samples. The values are stored in a MySQL database. There is a duplicate.

• Stored locally on sonata@10.1.49.80 (the server called sonata1“)
• USING MYSQL WORKBENCH: Stored on a Google Cloud VM instance. The server is user “db”, address “35.233.233.72”. This instance is available for anyone to perform SELECT commands only. I suggest using MySQL Workbench, available free at https://dev.mysql.com/downloads/file/?id=474219 to view the data.

There are 2 tables:

• various_sensors - this table contains sensor values from various locations on the dishes. Including the cryotemp. This data is sampled every 5 minutes going back to September 2014.
• feed_sensors - this table contains sensor reading from the feed control board and vacuum control board. Basically anything mentioned in http://setiquest.info/docs/feed-control-commands.pdf . Sample rate is every 4 hours. Note: March 17, 2019 the rate was changed to 30 minutes.

The code and usage documentation is at https://github.com/SETIatHCRO/ATA-Utils/tree/master/FeedSensors
