Table 2-3. - UNO Citation Data Format - 1983-84 CRADP field season

Data from the Citation II are broken into four data sets:

T24 - consisting of all data collected at the rate of 24 times per
second (every .04096 seconds actual)
T1 - consisting of all data collected at the rate of 1 time per
second (every .98304 seconds actual) and 1 second averages
of all T24 data
TeAM - consisting of all camera related data
PMS - consisting of all data collected by the PMS probes

T24~ T1~ and TCAM data sets all have a header record based on the same format.
The PMS data set does not have a header record. Each data set contains the data
collected from one flight. The data sets are stored on magnetic tape in the
following format:

Tape 1 - T24 data set; EOF; T1 data set; EOF; EOF
Tape 2 - TCAM data set; EOF; PMS data set; EOF; .EOF
(If needed because T1 or PMS data set is too long)
Tape 1A - T1 data set (continuation); EOF; EOF
Tape 2A - PMS data set (continuation); EOF; EOF

The PMS data set consists of two types of records. The slow record has a physi-
cal record length of 1920 bytes and a logical record length of 96 bytes. There
are 20 logical records per physical record. The 2-D record is 4128 bytes long.
These two record types are intermixed.

All tapes are 9 track, recorded at 1600 bpi.
REAL values contain 32 bits
INT4 values contain 32 bits
INT2 values contain 16 bits
BYTE values contain 8 bits

Listings of the four data sets can be provided by the Project Skywater Data
Manager or for more detailed information on the four data sets~ please contact:
