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.
