Write RFC file

Expected behavior

Output the trajectory in the RFC format.

Initial state

Variation: "GMT"

Input variables

Variable name	Description
floatdetails	The FLOAT section stored in an RFB file.
interpolated	Flag that tells if the line is interpolated
line_number	The line number
rafos_day	The rafos day
temperature	temperature array
pressure	pressure array
lat	latitude array
lon	longitude array
u	velocity array
v	veloctiy array
w	veloctiy array

Output parts

Header part

The header part always consists of the following text. All uppercase text is replaced by a variable:

** Float: FLOATNAME
** Variables: InterpFlag LineNum RafosDay  Temp  Pres  Lat  Lon  U     V     W
** Units    : #          #       #         degC  dbar  deg  deg  cm/s  cm/s  mm/s
** Dummies  : NA         NA      NA        -9.99 -999  999  999   999   999   999
** Cycle    : CURRENTCYCLE
** Launch position (Cycle Start position): LAT LON
** Surface position (Cycle End position) : LAT LON
** Cycle Start time             : YYYY MM DD HH mm ss (RAFOS day RAFOSCYCLESTARTTIME)
** Launch time                  : LAUNCHTIME
** Cycle End time               : YYYY MM DD HH mm ss (RAFOS day RAFOSCYCLEENDTIME)
** First surface Position time  : RECOVERTIME0 (RAFOS day RAFOSRECOVERTIME)

The 0 after RECOVERTIME is hard coded into the generation.

Data part

If the data part is empty, the following string will be appended:

** -------
 *   No trajectory information, flt not tracked.
