| 1-2 | Subsystem Indicator | 1-7 | The subsystem outputting the data product is:
|
| 3-4 | Product Code | 1-99 | Eash subsystem assigns its output (tape, disc, paper, plot, etc.) a unique number for identification. See Table 1 in Data Products Catalog for individual subsystem definitions. |
| 5-6 | Spacecraft Indicator | 1-7 | The data is from the following combination of spacecraft:
|
| 7-8 | Whole Julian date (high-order part) |
e.g., 244 | Leftmost 3 digits of the 7-digit whole part of the initial Julian data. |
| 9-10 | Whole Julian date (low-order part) |
e.g., 5700 | Rightmost 4 digits of the 7-digit whole part of the initial Julian date. |
| 11-12 | Fractional Julian date | e.g., 5000 | First 4 digits of the fractional part of the initial Julian date times 10000. |
| 13-14 | Processed Version Counter | 1-99 | A counter initially set to 1 and incremented by one each time the product is reprocessed. |
| 15-16 | Year Processed | e.g., 84 | The last two digits of the year of process date. The process date is the date (local time) when the data product was processed (or reprocessed) at Langley Research Center, Hampton, VA. |
| 17-18 | Month Processed | 1-12 | Month of the process date. January is 1 and December is 12. |
| 19-20 | Day Processed | 1-31 | Day of the process date. |
| 21-22 | Hour Processed | 0-23 | Hour of the process date. |
| 23-24 | Minute Processed | 0-59 | Minute of the process date. |
| 25-26 | Second Processed | 0-59 | Second of the process date. |
| 27-30 | Spares | 0 | Zero-filled spares to produce a record which is a multiple of 8 bits. |
