Welcome to easyspec’s documentation!

Tutorials

The instructions on how to use easyspec can be found in the GitHub directory “Tutorials”.

The main tutorials are:

• Image_cleaning_easyspec: here we will guide you on how to reduce raw long-slit spectroscopic data, i.e., we will show you how to trim, debias, dedark, flatten, remove the cosmic rays, and stack the data.

• spectroscopy_tracing_easyspec: here we will show you how to extract your spectra and calibrate them in wavelegnth and flux.

• spectral_analysis_easyspec: finally, we show you how to fit a model to each line of your spectrum with a MCMC approach and recover physical quantities such as redshift, dispersion velocity, FWHM, line flux and many more.

For a more advanced analysis, we recommend the tutorial

• spectral_analysis_fitting_a_line_with_two_Gaussians: here we fit the H \({\beta}\) line with two Gaussian components and also explore the MCMC posterior distributions.
