====== Data Structure ======

A **Reading** is one collection of three values from hardware within microseconds.\\
A **Timestamp** is a date and time in fractions of a second from Linux in GMT.\\
The **Angle** is the angular current position in degrees of the interferometer rotor.\\
A **Quadrant** is a cumulative sum of 1/4 wavelengths of light since program start. A quarter of a fringe shift.\\
A **Chunk** is used to reduce the volume in bytes of the contained Readings.\\
A **Turn** is a single, full rotation of the interferometer rotor.
 
**Reading** contains Timestamp, Angle, Quadrants\\
**Chunk** duration is 3 seconds, contains about 13 Readings.\\
**Turn** duration is 1 minute, contains 20 Chunks, about 260 readings.\\
**Hour** duration is 1 hour, contains 60 turns, about 15,600 readings.\\

Number of hours collected (1/1/22) is 12,000, about 187,200,000 readings.
