Bad Telemetry Intervals

List of intervals for which TIMAS data from the MRDF, LRDF, and PAD data products are not currently useable

Any TIMAS data in the MRDF, LRDF, or PAD data products acquired in mode 4 after 17 March 1996 and any data acquired in the interval before the second mode change after mode 4 terminates produces MRDF, LRDF, and PAD data products that can not be analyzed by the standard TIMAS ground software. The problem clears when the instrument mode subsequently changes. It will be possible to recover some, but not all, of the information in these data products obtained in the following intervals.

The source of the problem is in the way mass and energy look up
tables are handled during mode changes by the on-board softare.

Shown below are time intervals starting at the time mode 4 was
initiated, the ID number of the mode immediately following mode 4,
and the time of the mode change that clears the problem.

MRDF, LRDF, and PAD TIMAS data products are not currently useable for the following intervals

Data from the MS data product are useable for these intervals.
