GalSim based LSST simulation package
Set up the lsst_sims distribution, then enter the following from
this repo directory:
$ eups declare -r . imsim -t current
$ setup imsim
$ scons
Once you have eups declared a package like this, you only need to
execute the setup imsim command, and that command can be issued from
any directory. The scons build step needs only to be re-run if a
new command line executable is added to the bin.src folder.
The executables in the bin folder should be in your path and so
should be runnable directly from the command line:
$ imsim.py --help
usage: imsim.py [-h] [-n NUMROWS] [--outdir OUTDIR] [--sensor SENSOR]
[--config_file CONFIG_FILE]
[--log_level {DEBUG,INFO,WARN,ERROR,CRITICAL}]
file
positional arguments:
file The instance catalog
optional arguments:
-h, --help show this help message and exit
-n NUMROWS, --numrows NUMROWS
Read the first numrows of the file.
--outdir OUTDIR Output directory for eimage file
--sensor SENSOR Sensor to simulate, e.g., "R:2,2 S:1,1". If None, then
simulate all sensors with sources on them
--config_file CONFIG_FILE
Config file. If None, the default config will be used.
--log_level {DEBUG,INFO,WARN,ERROR,CRITICAL}
Logging level. Default: "INFO"
Similarly, by doing setup imsim, the PYTHONPATH environment
variable has been modified so that the desc.imsim module is available:
>>> import desc.imsim
>>>
