PIMA 2.13 release

[Leonid Petrov <Leonid.Petrov@xxxxxxxxxxx>]

Dear colleagues,

  New PIMA version was released. Here is the changelog:

2014.09.18  PIMA 2.13
            Added a rudimentary interface to atmosphere opacity
            and atmosphere brightness temperature computed from the
            output of numerical weather models with software SPD 
            (Slant Path Delay) http://astrogeo.org/spd.

            At the moment, PIMA has an ability to plot atmosphere
            opacity and sky brightness temperature.

            a) Added new task opag (OPAcity Generation).
               Requires spd package installed!
               Has keyword atmo_dir that requires the value:
               name of the directory with the state of the 
               atmosphere from numerical weather model in 
               HEB format. It computes the series of atmosphere
               opacity and antenna brightness temperatures
               for all stations participated in the VLBI experiment
               and time epochs within the time range of the session.
               PIMA prepares the control file for SPD and launches
               that program which makes all the work.
             
            b) Added new task opal (OPAcity Loading). This task
               loads into PIMA internal data structure the output 
               of computation of SPD that was generated by task opag.
             
            c) Extended task tspl (TSys PLot). Now it accepts keyword
               data that has one of the following values: 
               measured, nwm, and opacity.

               When value measured is specified, measured system 
               temperature is displayed.

               When value nwm is specified, atmosphere brightness temperature
               computed with SPD using the output of numerical weather 
               models is displayed. It is assumed that brightness temperature
               was loaded to PIMA data structures with task opal.

               When value opacity is specified, atmosphere opacity
               computed with SPD using the output of numerical weather 
               models is displayed. It is assumed that brightness temperature
               was loaded to PIMA data structures with task opal.
              
            d) PIMA has a new dependency: package spd_client. The tar-ball
               can be downloaded from http://astrogeo.org/spd

Have nice fringes,
Leonid
