These are the first files in the file system to receive collected data. Each file contains one day's data. The file is created on by iMac when collection starts. The storage medium is Google Drive.

When midnight is detected, the file is closed and a new file is opened for the new day. The file is switched based on Linux local time, which means that files are switched based on Daylight Savings time in the summer.

The file name of these file contains the date when the file was opened. The format of the file name, with leading directories is:

FOMMX/data/ZinsByyyymmddAR.txt

where yyyy is year, mm is month from 01 to 12, and dd is day from 01. The “A” following dd is a sequence letter within day. If the collection is interrupted, this character is changed for a continuation file with the same date.

These files are derived from the Original files. The data is resampled from about 4-5 samples per second in the Original files to exactly one sample per second in the Resampled file. The data format in the files has also been changed to comma separated variables (CVS). While the Original files may have part(s) of a day missing, these files have only complete days.

If someone wanted to do their own analysis of the data, this would be the set of files to use.

The format of the file name, with leading directories is:

FOMMX/dataC/ZinsCyyyymmdd.csv

where yyyy is year, mm is month from 01 to 12, and dd is day from 01.

The file has CVS format and the first row is the field names. The first three records of file ZinsC20200126.csv are as follows:

timeMST,         turns,  azrotor, cumazrot,  quadrant
1580022000.81,   484.0,  117.0,   174357.0,  -1411.2
1580022001.8425, 484.0,  123.0,   174363.0,  -1410.0

• timeMST - This is the Linux time stamp. (Nothing to do with Mountain Standard Time)
• turns - Whole rotations of the rotor of the interferometer, derived from rotary encoder.
• azrotor - Azimuth of the rotor, in degrees, derived from rotary encoder.
  • Azimuth is zero when the arm with black tape is at true North.
  • Azimuth increases when the arm with black tape moves from North toward East.
• cumazrot - turns * 360 + azrotor
• quadrant - The interferometer determines the phase difference of the light from the two arms.
  • A phase difference of $\pi/2$ is one quadrant.
  • The quadrant value is the count of quadrants detected since the collection program on the interferometer rotor began execution.
