Project description

Readme file

Implementations and versions

  • Implementations in the current version (Beta 0.1):
    • Grain shapes: Implemented CDE grains

    • Grain sizes: single grain size

    • Optical constants in database: olivine (amorph and crystalline), carbon, ices

    • Benchmarked with Michiels code (Min et al 2009)

  • Next version (Beta 1.0)
    • Grain shapes: implement MIE and CDE grains

    • Grain sizes: single grain size

    • Optical constants in database:
      • silicates (olivine and pyroxene, amorph and crystalline)

      • oxides

      • carbon

      • ices

      • Able to use your own optical constants

  • Future versions:
    • Grain shapes: implement MIE, DHS, GRF and CDE grains

    • Grain sizes: single grain size and grain size distributions

    • Optical constants in database:
      • Full JENA database avaliable in the SQLite database

      • Able to use your own optical constants

    • Other functions:
      • Enable saving of the opacities in a local SQLite DB

Installation:

  • PyPi:

    run: pip install opacity_calculator

  • Github
    • Download the files from github. Inside the opacity_calculator directory type (if you need permissions, with sudo): python setup.py install

    • To test if it works type python to go into python and then “import opacity_calculator”

Introduction

Coming…

Getting started: an example

If you have the opacity_calculator installed and want to test how it works and plot a spectrum with the matplotlib package. Go into python and type:
  • import opacity_calculator as oc

  • opacitiesForsterite = oc.getOpacity(“fo050”, 1.0, print_console_output = True)

  • import matplotlib.pyplot as plt

  • plt.plot(opac.getX(), opac.getY())

  • plt.show)

If you want to try another mineral, check the content of the database in the following way:
  • import opacity_calculator as oc

  • oc.printDatabase()

  • You can use the labels in the label column to generate opacities with the getOpacity function.
