LSFExtractor 0.0.1

A Python module to estimate the Line Spread Function

LSFExtractor

Description

This module enables users to extract the Line Spread Function (LSF) from any type of spectral cube. The provided code automatically handles multiple axes in the datacube.

Currently, the code estimates the LSF only for ALMA data cubes, but we are actively developing support for additional types of cubes.

Getting Started

Installing

Releases are registered on PyPI, and development is occurring at the project's GitHub page.

Executing program

First we need to import the module to the python script or notebook.

import LSFExtractor as lsf

The module executes by creating an instance of the class with just the path to a cube file, and then using the get_LSF method.

cube = lsf.Cube('path_to_file')
cube.get_LSF()

The method returns a list of length three corresponding to LSF, LSF lower error, and LSF upper error, respectively. It can also be accessed using the .LSF attribute of the class

 LSF, LSF_lower, LSF_upper = cube.LSF

The class includes the method .save_LSF(path, format = '.3f', write = True) which creates an Astropy QTable with the code's output and saves it as an ASCII table in the file named path_LSF.dat

cube.save_LSF('new_path')

More documentation can be found inside the .py files.
