This package has been tested on several Linux distributions including
RedHat 7.0, 7.2, 8.0 and 9.0. It ought to work on most recent distributions
of Linux. It has also been tested some times ago on SunOS.
Content of the package:
+-- clean-dist: a small script to clean up the distribution
+-- install_all: the installation scrip
+-- jmp/: the Wavelet path directory
+-- pipematt/: the S-Extractor path directory
+-- README: this very file
How to install:
1: retrieve the package "detect-pack-yyyymmdd.tgz" where yyyy stand for the
year, mm for the month and dd for the day of the release. Put the file
in the installation directory .
2: untar the file in the installation directory:
...$ tar xzf detect-pack-yyyymmdd.tgz
...$ gzcat detect-pack-yyyymmdd.tgz | tar xf -
This will create a directory called "detect-pack" under .
3: Run the install script "install_all"
...$ cd detect-pack
...$ ./install_all [-p |--prefix ]
where is the directory where the package will be
installed. Usually, this is "." or /detect-pack
4: Add some directories to the PATH and LD_LIBRARY_PATH environment
...$ export PATH LD_LIBRARY_PATH
Be sure to respect the order of directory in PATH.
At this point, you should have a working detection package.
How to run the detection package:
This package assumes that there exists a directory tree structure that
contains the 3 images of a same field in each directory. This structure is
listed in a file using the script "finddirs.sh". This script assumes a
directory tree structure like
< field-name >/< chip-name=c??|chip??|im?? >
But this can easily adapted to your personnal needs.
This creates a file named "directory" (not a good choice obviously) in the
Using this directory list, one runs "initfind.sh" to find the correct fits
images and determine the FWHM of each image, producing a file called
"proc-these-file" in each directory and a list of directories to process,
"find.input" in the current directory.
...$ initfind.sh [-d < dir >] [-p < prefix >] [-s < suffix >] [-f < seeing >] [-h|-?]
< dir > is the directory where the file "directory" is located.
< prefix > and < suffix > are the prefix and suffix of the image names:
is the default FHWM of the images.
-h or -? give a very limited help.
Now you can run the "findall.sh" script that will run the detection
pipeline on each field.
...$ findall.sh [-d < dir >] [-rn < min_rate >] [-rx < max_rate >] [-ang < angle >] [-aw < openning angle >] [-h|-?]
< dir > is the directory where the file "find.input" is located.
< min_rate > is the minimum rate of motion for searching.
< max_rate > is the maximum rate of motion for searching.
< angle > is the mean direction of motion, expressed in degrees,
anticlockwise, from the right horizontal direction.
< openning angle > is the openning angle about the mean direction for searching.
-h or -? give a very limited help.
For each directory where things go right, the script write its name in the
file "processed" in the directory < dir >, and touches a file "processed" in
the field/chip directory.
The result of the S-Extractor path is given in "< image1 >.moving.matt", the
result of the Wavelet path is in "< image1 >.moving.jmp", and the combination
of both is in "< image1 >.cands.comb".
