Experiment Configurations

Three status configurations have been used in the CRUISE portion of the Voyager-1 mission while five status configurations have been used in the CRUISE portion of the Voyager-2 mission.

Nominal telescope conditions are indicated by a 00 in the rightmost byte of each status word for words 5 - 10 (05 - 0A in the left byte of each status word).

Status Byte Meanings:

0020 High Volt. enable indicator

0308 LB1 power off

0580 delete LA3 terms

0582 delete LA3 terms, disable LET B

0600 nominal

0680 delete LC3 terms

0780 delete LB3 terms

0880 delete LD3 terms

0A00 nominal

0A04 delete D3 terms

0D04 Het 1 gain set high

0D0A Het 1 and Het 2 auto gain flag on

Other Status Bytes sometimes seen:

08A0 Het 2 delete C1 and B1 terms

0D05 Het 1 and Het 2 gain set high

0583 disable LET A, disable LET B PHA analysis

The Low Energy Telescopes and The Electron Telescope for both space craft are frequently in non-nominal status states during the CRUISE portion of the mission. To access non-nominal rate data in our system requires input to our FLUXPLOT program (which makes data summaries) of the exact COINCIDENCE LOGIC EQUATION described by the non-nominal instrument status. To handle both nominal and non-nominal times we have requested both states for the lifetime cruise periods. Therefore, users of this NSSDC data need to be aware of the correct status condition for times of interest, and look at the corresponding data quantity for our submission, in order to not be confused by thinking there is no data for those quantities affected.

Voyager-1 Excluded Times

The following times (localized and non-localized data blips) have been excluded from our NSSDC data. Whole single exclude days are probably data blips which were never localized.
