FOMMX follows the principles and terminology of Miller(1933) as much as possible. In particular, the words sheet, column, and row follow Miller's usage.

Miller used a data collection spreadsheet preprinted with rows and columns(p213). When a sound signal occurred, Miller estimated the fringe shift and called it out. An assistant recorded that number on the spreadsheet.

As the interferometer turned through one revolution, the numbers were entered in one row. The sound signal occurred sixteen times per revolution, and the data for each was recorded in the corresponding column.

The following list describes the data structure and timing used in FOMMX, with the corresponding value for Miller. Numbers in [square brackets] or {curly braces} or <> are for planning new system.

• –96 Sheets per day(=24*4). (Miller 1-10 estimated)
• There are 360 degrees per turn of the interferometer.
• 18[24]{30}<36> Columns per turn. (Miller 16) More is expected to lead to better fit of Cosine to turn by rejecting noise
• 20[15]{12}<10> Degrees per column. (Miller 22.5) Fewer will increase data reduction time.
• 60 Seconds per turn. (Miller 45 estimated)
• 3.33 Seconds per column. (=60/18).
• 4,35 Readings per second.
• 14.5 Readings per column. (Muller 1)
• 15 Rows (Interferometer turns) per sheet. (Miller 20)
• 900 Seconds = 15 Minutes, per sheet. (Miller 900s estimated) lesser importance
• == 4[2] sheets/points per hour (point on 4-epoch plot) 4 too many
• — 60 minutes per hour
• === 15[30] minutes/turns/rows per sheet
• == 18[30 ] columns per sheet row/turn/minute (18 too small for fit, esp for Half) greater importance
• …
• === 96[48] Sheets/points per day, continuous, automated. (Miller's manual collection admitted far less)
• ..
• .
• 270 = 18 * 15 Cells per sheet. (Miller 320)
• 25,920 = 96 * 270 Cells per day
• 375,950 Readings per day
• 14.5 = 375,950 / 25,920 Readings per Cell, approximately. (Miller 1)
• 12,000 hours total collected.
• 500 days (equivalent) total collected
• 187,975,000 = 500 * 375,950 readings total performed.
