Processing of STAFF FFT (Double Star) calibrated data
from level 2 binary files. These file are generated by the fftl2 program (Keith Yearby, University of Sheffield).
PRASSADCO is a computer program designed to analyze multicomponent measurements of electromagnetic waves.
It implements methods used to estimate polarization and propagation parameters,
such as the degree of polarization, sense of elliptic polarization and axes of polarization ellipse,
the wave vector direction. The results can be represented in different visual and numerical formats.
The main purpose of this distribution is to provide possibility to generate preview
postscript files from the level 2 data.
Instructions:
- Download files pras.pro, read_fftl2.idl, pra_template.ini, and 03281018_l2v102_def.dat
- Under IDL (ver 5.5 and higher) type pras,'03281018_l2v102_def.dat'
- A new ascii log file 03281018_l2v102_def_log.txt,
a new binary data file 03281018_l2v102_def_1022_1024_sm.dat, and
a new resulting postscript file 03281018_l2v102_defO_pra00.ps will be generated in the same directory.
- The same procedure can be used for different level 2 files.
Distribution:
- pras.pro ... The main IDL procedure (Parameter: name of the level 2 binary file, Uses: read_fftl2.idl)
- read_fftl2.idl ... IDL library of PRASSADCO and read_FFTL2 procedures.
- pra_template.ini ... Configuration file (ASCII) defining the output postscript file.
- 03281018_l2v102_def.dat ... An example input level-2 file for testing purposes.
- guide.pdf ... PRASSADCO documentation (Cluster version) - a 2 MByte pdf file.
Can be used to modify pra_template.ini
