| + | The Fiber-Optic Michelson-Morley Experiment, FOMMX, data collection follows the principles and terminology of Miller (1933). | ||
| + | |||
| + | Miller used a data-collection spreadsheet preprinted with rows and columns (p213). | ||
| + | When a signal occurred, Miller estimated the interferometric 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 occurrence was recorded in the corresponding column. | ||
| + | |||
| + | The following list describes the data structure and timing used in FOMMX. | ||
| + | |||
| + | * Data Collection File: 1 Day. | ||
| + | * Sheet: 30 minutes, 48 per Day | ||
| + | * (A sheet is analogous to Miller' | ||
| + | * Row, Turn: 1 minute, 360˚ per Turn. There are 30 Rows and Turns per Column and Sheet. | ||
| + | * (A Turn is one full cycle of rotation of interferometer arms.) | ||
| + | * (A Row is a horizontal set of cells.) | ||
| + | * Column: 2 seconds, 12˚ per column. There are 30 Columns per Row and Turn and Sheet. | ||
| + | * Cell: A single number. There are 30 cells per row and 30 cells per Column. | ||
| + | * Reading: 0.23 seconds, 4.35 per second. Miller had one reading per cell. | ||
| + | * (A Program reads a set of values from electronics and stores them.) | ||
| + | * Readings per hour 15,660. | ||
| + | * Readings for 12,000 hours in 2020, 2021: 187, | ||
| + | | ||
| - | * 96 = 24 * 4 Sheets per day. (Miller 1-10) | ||
| - | * 18 Columns per sheet. (Miller 16) | ||
| - | * 20 Degrees per column. (Miller 22.5) | ||
| - | * 15 Rows (Interferometer Turns) per sheet. (Miller 20) | ||
| - | * 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. | ||
