PyStacker

PyStacker is a wrapper that performs the spectral stacking code on either an existing PyStructure database or a set of 3D data cubes (fits files). When executing via the terminal the -c parameter sets the configure file and -m the mode.

Instruction:

There exist two modes how the PyStacker code can be utilized:

1. With a PyStructure Database

In case a database (as a .npy file) exists, the code can be executed by adjusting the parameters in the configur file as shown in run_PyStructure.conf. Then simply execute in the terminal with:

python PyStacker.py -c run_PyStructure.conf -m PyStruc

where PyStruc sets the mode on how to execute the program.

Note: You can provide optional parameters (list: TBD). You can also simply remove these parameters (or add pre-existing optional parameters) at the end of the configure file.

2. Only with 3D Fits Datacubes

The code now also works without a pre-existing PyStructure database. 3D Datacubes are required as input. These have to be convolved and regridded to the same resolution and the same grid. In addition, a velocity map with which to shuffle the spectra, must be provided. It can be executed by adjusting the parameters in the run_3DCube.conf file:

python PyStacker.py -c run_3DCube.conf -m 3D_cube

where 3D_cube sets the mode on how to execute the program.
