DESCRIPTION = "
This table contains selected channelized spacecraft engineering or DSN
monitor data, edited and reformated to PDS standards. Engineering files
have names of the form CSVxxxxx.ECH; files of DSN monitor data have
names of the form CSVxxxxx.MCH.
Each row in the table contains 7 columns: time, channel ID, type of raw
data (A for alphanumeric, D for digital, F for floating-point, I for
integer, S for status, or U for unsigned integer), a pointer to the
column for best data (5, 6, or 7), a field containing the data number
(DN) or value, the corresponding integer value (if available), and the
corresponding engineering or floating point value (EU). The table is in
ASCII format; each row has 82 bytes with the last two bytes being an
ASCII carriage-return line-feed pair.
Table values were derived from an ECSV file which in turn was derived
from a file of channelized engineering or DSN monitor data using DMD.
This subset of Mars Global Surveyor engineering channels was selected
by the MGS Radio Science Team and includes (from the channel set file):
M-0300 RCT EU ANT_A_ANT_NUMBER
M-0304 RCT EU ANT_A_EL_ANG
M-0305 RCT EU ANT_A_AZ_ANG
