carronr/grapa: Version 0.5.0.0

Grapa is a python package providing a graphical interface and the underlying code dedicated to the visualization, analysis and presentation of scientific data, with a focus on photovoltaic research.

New major version number, indicating that grapa can installed using pip! Otherwise no big changes in the software.

Additions:

• Can now reads some reflectance files (Perkin Elmer spectrophotometer).
• CurveSpectrum has beed significantly extended, to offer some support to reflectance and transmittance curves. The following functions were added:
  • Correct for instrumental response, stored in datatypes/spectrumInstrumentalResponses.txt.
  • Compute the absorptance, defined as A = 1 - R - T
  • Estimate the absorption coefficient alpha, with input the thickness of the layer. A simple is also provided to account for the absorption in the substrate (see file datatypes/spectrumSubstrates.txt) The last 2 functions request selecting a transmittance/reflectance curve. More details are given in the manual. Modifications:
• Added options to easily change the calibration of XRF files Under the hood:
• Revised the code for opening spectrum files.
