Download Extraction and Viewing Tools

Below are the tools for extracting data (signal power and times) from FSL files and creating summary files (.sum files) under DOS. These tools *only* work with the SCINTMON Scintillation Monitor (running in DOS).

fextract.exe v1.41
sum.exe v1.10
scanfile.exe v1.32
helvb.fon Helvetica font needed by scanfile

Below are tools for extracting data from VERSION 4 FSL files under Linux. These tools only work on the most recent Linux version (Cascade). To download these, right click on the file and select 'Save Link As...'. Please only use the code fslextract4 and lsum4. The other versions may not work correctly.

fslextract.tar.gz v1.41
lsum4.tar.gz v4.01

Download MATLAB scripts for creating summary plots

Below are MATLAB scripts that read in .sum (summary) files generated by sum.exe (see section above) and generate a summary plot of the satellites' signal power throughout the evening (cppow2.m), S4 index throughout the eveing, and an elevation/azimuth plot with overlayed S4 index (cpelaz2.m), also throughout the evening. Note that currently these scripts DO NOT run in Octave, which is primarily due to differences in the subplot() command.

cppow2.m v2.0
cppow2.m v1.0
cpelaz2.m v2.0
sum_elaz.m required by cpelaz2.m
arrow.m required by cpelaz2.m

Sample Summary Plots Generated Last Night at Cornell University

These plots were generated from the .sum file from the previous evening.
