LiMe: A Line Measuring library
This library provides a set of tools to fit lines in astronomical spectra. Its design aims for a user-friendly workflow for both single lines and large data sets. The library provides tools for masking, detecting, profile fitting and storing the results. The output measurements are focused on the gas chemical and kinematic analysis.
These are some of the features currently available:
Non-profile and Gaussian profile emission and absorption line measurements.
The user can include the pixel error spectrum in the calculation.
The Multi-Gaussian profile parameters can be constrained by the user during the fitting.
Tools to confirm the presence of lines.
Static and interactive plots for the visual appraisal of inputs and outputs
Line labels adhere to the PyNeb format.
The measurements can be saved in several file types, including multi-page .fits, .asdf and .xlsx files
