The Engineering Record will be used in the engineering EDR and all normal-rate Science EDR's. The Engineering Record Format is described in Figure B-2, the Standard Record Header in Appendix C , and the Engineering Data Block in Figure B-4 and Table B-1. This Engineering data block contains engineering data for 60 EMF for both 10 and 40 bps data. Each channel will appear in the same location during a readout sequence. For 40 and 10 bps data, a readout sequence is accomplished in 12 and 48 minutes respectively. Decommutation must be done with the last Decom Map preceeding the Engineering record.

The Engineering EDR will contain Engineering Records, Imaging Status Records, Monitor Records, and Decommutation Map Records. The Decom Record is described in Appendix A. The Engineering record formats are shown in Figure B-2. Each of these records utilizes the Standard Record Header described in Appendix C, with some re-definitions noted below. The data block descriptions for Imaging appear in Table B-1.
For the Engineering Record, only the first 60 MF locations for the DPI fields will be used to flag the 60 EMF of the record. The remaining 20 locations and the GCI fields will be spares. The DQSE and GCI fields will be zeroed.
The Imaging Status Record will utilize the first 60 MF positions for DPI. DQSE and GCI fields will be zeroed. The first 4 MF locations for each field will flag GS MFs 1, 12, 21, and 31 of the 48-second science record from which the first ISS parameter set was extracted. The second 4 MF positions will flag the same MFs corresponding to the second set of parameters, etc.
The Engineering Record will be used in the Engineering EDR and all normal-rate Science EDR's excluding PWS. The Engineering Record Format is described in Figure B-4, the Standard Record Header in Appendix C, and the Engineering Data Block in Table B-3. This engineering data block contains engineering data for 60 EMF. Each channel will appear in the same location during this 48-minute record. Decommutation must be done with the last decom map preceding the Engineering Record.
The Engineering EDR will contain Engineering Records and Decommutation Map Records. The Decom Record is described in Appendix A. The record formats of the former two record types are shown in Figure B-2. Each of these records utilizes the Standard Record Header described in Appendix C, with some re-definitions noted below. The data block descriptions for these records appear in Figures B-2, B-4, B-6, and Tables B-1 and B-3.
