Data Log

5.7

.Ihhhhmmss

at the beginning of the line creates a new time
frame: the digits immediately following give
the time interval for output (the time
formatting need not be complete). All lines
until the next .I, .F or file end are taken to
belong to this time frame. The minimum time
interval is 10 seconds.

.P

position in the format:
ddmm.mmmN[S] dddmm.mmmE[W]

.C

position in the format:
[-]d.ddddddd,[-]d.ddddddd—the first number
is latitude and they are comma separated so
that position is easier to import into a
spreadsheet. Negative is West or South.

.D date

as

dd/mm/yy

.N date

as

mm/dd/yy

.T

time as hhmmss

.Ann

Average of the nnth variable during the time
interval

.Lnn

final value of the nnth variable at the end of
the time interval

The variate numbers can be read in the file J_VARS.D (please note that
any editing of this file directly should only be undertaken if you are
confident you know what you are doing).
