; read_gla01_wf.pro: This program reads from GLA01 and outputs the uncompressed ; waveform values in volts. Forty shots are output for each ; data record. The output for each shot is: unique index ; number, shot time, number of samples in the shot, shot ; number, and the uncompressed waveform values in volts. ; ; Note: The waveforms have been reversed such that the leftmost ; gate is the first received by the satellite and hence the highest ; elevation (or shortest distance between the satellite and the ground). ; ; 2005 April T. Sidel ; ; SYNTAX: ; read_gla01_wf ; ; NEEDS A CONTROL FILE TO RUN: ; Assumes that the name of the control file is read_gla01_ctrl.dat and it ; resides in the directory that read_gla01_wf is run from. ; ; EXAMPLE OF A CONTROL FILE: ; ------------------------------------------------------------------------------- # Input File (GLA01) INPUT_FILE = /SCF/product_sets/current/L2_2107/GLA01_017_2107_003_0379_1_01_0001.P0501 # Data release number of input file RELEASE = 17 # Beginning time to print START_TIME = 140781825.9 # Number of seconds to print DELTA_TIME = 2 # First data record to print REC1 = 1 # Number of records to print starting with first record above # NREC = 0 will print to the end of the file NREC = 1 # Output File (Optional) OUTPUT_FILE = out_file.dat =END ------------------------------------------------------------------------------- ; ; Note on keywords: ; Use START_TIME/DELTA_TIME or REC1/NREC to specify records displayed. ; If both sets are specified, then START_TIME/DELTA_TIME will be used. ; ; REQUIRED PATH: ; If the user wants to run the program from a directory other than ; the directory that the source files are in, xx, the following command ; needs to be applied to include the source code directory: ; !path=+"xx:"+!path ; ; Example to run the program: ; idl ; !path=+"/SCF/IDL/IDLreadGLAS:"+!path ; .run read_gla01_wf ; read_gla01_wf ; ------------------------------------------------------------------------------- Other Modes of Running: This software also runs under the IDL virtual machine. To do so: - Edit the read_gla01_ctrl.dat control file as desired - Type at the Unix command line: idl -vm='read_gla01_wf.sav' - Click on the flash screen To run on the PC: ----------------- - Edit the control file, read_gla01_ctrl.dat, and modify as necessary (an output file needs to be specified) - Bring up IDL - Go to File/Preferences and set IDL "Startup" and "Path" accordingly - Type at the IDL prompt: .run read_gla01_wf - Type at the IDL prompt: read_gla01_wf To run on the PC using the IDL virtual machine: ----------------------------------------------- - Edit the control file, read_gla01_ctrl.dat, and modify as necessary (an output file needs to be specified) - Click on read_gla01_wf.sav - Click on the flash screen
