A.8.6 DI Commandables<br />

<strong>The</strong> DI commandables file contains the command settings of the “Data Ingest” task. This task<br />

performs the basic computations on raw event data from the array. <strong>The</strong> events are transformed into<br />

light curves on various time scales, survey DPHs, and other products. While a detailed description<br />

of every field in this file is beyond the scope of this document, the major categories are:<br />

• Trigger thresholds (TRIGEN,THCERT,THLONG,THPOSS,THPROJ,THSHRT);<br />

• Noisy detector management (NHOTKL, NHOTLM);<br />

• Survey and calibration intervals (SURDUR, AM2DUR);<br />

• Survey and light curve energy bin edges;<br />

• Automatic script names;<br />

• DM calibration coefficients;<br />

A.8.7 Debug Stream<br />

<strong>The</strong> <strong>BAT</strong> produces continuous logs of its activities. This is primarily used for debugging purposes.<br />

<strong>The</strong>re are actually two separate streams, the “debug” stream, which contains the <strong>BAT</strong> flight software<br />

debugging information, and the “shell” stream, which is a log of the VxWorks command shell.<br />

<strong>The</strong> files contain ASCII substrings of variable length. <strong>The</strong> LENGTH column determines the length<br />

of the substring, and the ASCII column contains the actual character data. Note that this log<br />

information is not meant to be used for any scientific purposes.<br />

EXTNAME = ‘DEBUG LOG’ or ‘SHELL LOG’<br />

Name Format [Units] Comment<br />

LOGSEC 1J [s] [s] Spacecraft MET of log entry<br />

LOGSUBSEC 1I [s] [s] Spacecraft MET subseconds of log entry<br />

APID 1I Application ID data originally from<br />

LENGTH 1I Log entry length in characters<br />

ASCII 215A Log entry text<br />

A.8.8 Trigger Diagnostic Tables<br />

<strong>The</strong> trigger system of the <strong>BAT</strong> flight software produces periodic table dumps of the on-board trigger<br />

tables, and are stored in trend data on the ground. <strong>The</strong> trigger tables are: “long”, “short”, “rate”,<br />

and “image”.
