Blog: [Question] How to measure spectral line equivalent widths
Question from Dan Feldman:
Hi, I'm working on writing or finding a Python script/module that can automate the measuring of equivalent widths for both emission and absorption lines, fitting various line profiles (e.g. Gaussian profiles, Voigt Profiles). How do I go about this?
For instance, Ben Weiner commented on a blog post here http://www.astrobetter.com/spectral-line-analysis-tools/#comment-3349 and I basically want to know ...

Snippet: Save sherpa fit and conf results to a JSON file
After doing a fit with Sherpa you may want to dump all the results to a file for later processing or inspection. The following snippet writes the results from model fitting and confidence estimation to a file using the JSON format for data serialization. This format is widely supported in other programming languages and is also human-readable.
import json from sherpa.astro.ui import get_source, get_fit_results, get_conf_results src ...
