Windmeter on platform

    The windmeter is mounted on the platform. It comes down from the platform on a fiber into jon hagens windmeter box. This box supplies a analog meter output. It also presents the voltages for velocity, direction to front panel bnc's and to rear panel bnc's that are read by a sbc computer to log the info.
    see: Dana's notes on the windmeter (oct08)

    The logging of the data:

• The program running on the sbc is called wind_data.c. It is located in /home/aoui/develop/sbc/wind_data.c.
• The mjd in the output file comes from this computers clock
• A tcl/tk program called newwindmeter.tcl runs on the obsdisplay computer. It's  code is in /export/wind/newwindmeter.tcl (on obsdisplay)ter.c.
  
•  It reads the data, displays the info on the monitor to the left of observer2 and it writes the ascii data to the daily logfile in /export/wind. The time stamp in the file hhmmss comes from obsdisplay's clock.
• old version: An display program called windmeter.c runs on the obsdisplay computer. It's source code is in /home/aoui/display/wind/windmeter.c. It uses jeff's sockLib routines to connect to the sbc wind_data.c program. It reads the data, displays the info on the monitor to the left of observer2 and it uses the log_msg() routine (/home/aoui/lib/loglib.c) to write the data to the disk file. The time stamp in the file hhmmss comes from obsdisplay's clock.
• It looks like the jd time stamp in the datafiles drifts off (the sbc clock is probably not too stable). The hhmmss time stamp looks accurate since obsdisplay is running ntpd.

Idl code:

• /share/pkg/rsi/local/phil/wind/
• There are a set of routines to read in a months worth of logfiles and stores them in an idl.sav file. These save files are currently in /share/gx260s1dat1/wind (a usb disk).
• A set of routines to generate monthly/yearly plots.. see the readme file in teh idl/wind directory.
