This repo hosts the pipeline for HESP echelle spectrograph.
The repo can be cloned using git clone
git clone https://github.com/arunsurya77/hesp_pipeline/
it has following files
- bin directory with the source files and supportfiles
- req.txt which has the list of python packages required for the installation
- hesp.config the config file for the pipeline
Make sure you have pip installed in your system. You can install it in ubuntu by
sudo apt-getinstall python-pip
or in Fedora by,
yum install python-pip
Use pip to installthe packages listed in req.txt
sudo pip install -r req.txt
Once the packages are installed copy the bin directory to a location in your home directory. This could be inside a subdirectory also. Copy hesp.config to your home directory. hesp.config has to be directly in your home directory and notinside any subdirectories .
Edit your hesp.config and give the exact path to the bin directory in the path= line in
Config subsection of hesp.config.
Now to make the python scripts inside the bin directory executable. Go to the bin directory and use the command
sudo chmod a+x hesp_*
In Fedora one can accomplish the same using chmod command in root #. Now the bin directory has to be added to the linux environment variable $PATH to be accessible at differentlocations .
For this edit your .bash_profile or .bashrc file to add
PATH=$PATH:~/hesp/bin export PATH
where ~/hesp/bin is the path ofthe hesp source files.
Depending on .bashrc or .bash_profile you used you will need to open a new terminal or
login again for the PATH variable to be active.
hesp_createlist : Create the files.txt with the list of files and related info used for reduction.
hesp_preproc : Preprocessing of the files including, Bias Subtraction, Overscan Correction, Trimming and Cosmic Ray Correction
hesp_extract: Extract the orders from the processed files. This command will extract all the files listed in files.txt
hesp_extract_file : Extract only a single file given as argument ofthe command
hesp_traceview: View the trace overplotted on the image file given as the argument.
hesp_traceshift : Adjustthe trace by shifting interactively and update the global traces in the bin directory.
hesp_addwave: Create wavelength calibrated spectra for a list of files given as argument.
hesp_recalib: Find outthe global shifts in ThAr spectra and adjust and re-calibrate the wavelength solution accordingly
hesp_view : Interactive viewing ofthe wavelength calibrated spectra
