misfits

misfits is an interactive tool to measure spectral features in spectra of transients and approximate their errors.

Installation

Setup virtual environment (optional, but recommended)

$ cd /directory/for/virtual/environments
$ python3 -m venv --copies misfits
$ source misfits/bin/activate

Installing misfits

$ cd /directory/of/misfits
$ pip install -r requirements.txt
$ python setup.py install

Example

Estimate an error spectrum from a low-pass filtered spectrum and use it when fitting Gaussians to measure line velocities and their errors.

$ misfits lowpass rawsmooth velocity.gaussians montecarlo spectrum.fits

Run $ misfits --help for a list of methods and arguments.
