A second optional parameter can be used to pass the name of a configuration file. This file must be located in ~/etc e.g. ~/etc/params_Hawaii.cfg . If no optional parameter is supplied, the configuration is read from ~/etc/params.cfg .
This program is similar to Plott_WERA_Sort_RCs_Beam, except that for a given range cell the beam is steered +/- 70 degrees.
Plott_WERA_Sort_Ang_Beam reads all information needed on number of channels, length of timeseries, etc. from the header (first 512 bytes of data file) and the following parameters for PARAM_UV.CFG (VMS) or /home/wera/etc/params.cfg (Linux):
Values in PARAM_UV.CFG or /home/wera/etc/params.cfg:
AUTO_SCALE = .TRUE. !.true. = use auto scale
C Name of WERA Gain File
C
GAIN_NAME = '/home/wera/etc/wera_gain.dat'
!The following 7 parameters allow simultaneous use of a linear and
!a square array within the same WERA system. They provide a mapping
!of receiver channels to antenna numbers. A value of '0' indicates that
!this antenna configuration does not exist in the actual WERA system.
!
ARR1_001 = 1 !First antenna# in linear array
ARR2_001 = 16 !Last antenna# in linear array
ARRD_001 = 9.35 !Distance between elements [meters]
!Name of file for FullCalibration
FCAL_001 = '/home/wera/etc/LaRevellata.fullcal'
!Name of file for linear array spacing
DIST_001 = 'antdist_LaRevellata.asc'

Graphics can be generated for all range cells.
The dynamic range shown in the figure has a fixed reference point: The ADC's maximum input voltage of +/-10 Volts * Gain Ramp refers to 0 dB.
