For a full list of "science numbers" (decimation identification number in the data packets) and instructions on how to read them from the data files go to Conversion Table Between IDPU Version # and Decimation Table ID.
The decimation depth and the top decimated energy level depend on the SSR level and the attenuator state. The tables used are:
| Quiet/CRAB: | T5 | ("Crab Ops") |
| Very Quiet: | T6 | ("Very Quiet Sun") |
| Normal: | T3 | ("Quiet Sun") |
| Active: | T4 | ("Active Sun") |
The rear segments are decimated at high-magnetic-latitude zone ONLY (day or night). The used tables of top decimated energy level and decimation depth are:
| Normal: | decimation below channel 4*128 (approx. 195 keV), 3/4 removed | (code: 43) |
| Active: | decimation below channel 8*128 (approx. 390 keV), 3/4 removed | (code: 83) |
| Vigorous: | decimation below channel 8*128 (approx. 390 keV), 5/6 removed | (code: 85) |
