21-35 D15.6 Antenna axis displacement in meters. 0. M
36-50 D15.6 Nominal received wavelength in microns. 0. M*1.0D-6
( 0. indicates nominal wavelength will
be used from observation file as
supplied by the Tracking Data
Formatter Program.)
51-65 D15.6 Turn around factor (TRF). 1.
(TRF=Wavelength trans./wavelength rec.)
NOTES:
[1] Inclusion of an INSTRMNT card which is blank except for columns 1-8
negates any previous INSTRMNT card and reverts back to the station
complement defaults.
[2] A "7" in column 10 requests reading the station height offsets from
unit 23. The following quantities are read:
Col
1-6 IYMD I6 - year, month, day (YYMMDD)
7-10 IHM I4 - hour, minute (HHMM)
11-20 SEC F10.1 - seconds
21-22 - not used
23-30 NSTA I8 - station number
36-59 AOFF D24.16 - height offset
If the file connected to unit 23 is not present or is empty, no station
height offsets are applied. Otherwise, the station height offset is
chosen as the value on the record whose time is less than or equal to
the current time. A time before the start of the table takes the
value of the first offset for that station; a time after the end of
the table takes the last value in the table.
[3] A "8" in column 10 requests reading the station pressure values from
unit 23. The following quantities are read:
Col
1-6 IYMD I6 - year, month, day (YYMMDD)
7-10 IHM I4 - hour, minute (HHMM)
11-20 SEC F10.1 - seconds
21-22 - not used
23-30 NSTA I8 - station number
36-59 pmean D24.16 - pressure offset (mbar)
60-83 scale - pressure scale factor
The reading of unit 23 and the assignment of values is done as for
option 7. (See NOTE [2] above)
UNITS: KM =Kilometers; M =Meters ; S =Seconds ; M/S=Meters per second
DEG=Degrees ; RAD=Radians ; AS =Arc seconds; MAS=Milli-arc seconds
IF CARD IS OMITTED: No instrument correction will be applied.
