[PR 1035](https://github.com/PlasmaPy/PlasmaPy/pull/1035): PRad Bugfix ## Attendees * Erik * Peter ## Action Items ***Erik*** * Look into error estimate functionality for Thomson Spectra * See where LaPD is at with integrating Thomson scattering * Make a decision on if we should merge Thomson Spectra w/o (or before nailing) the error estimate functionality ## Minutes * Grids 3...persistent interpolators * Grids 4...review and minor fixes/refactors * PR 1049 mesh grids * transfers the shadow of a wire mesh to the detector plane * current approach * mesh is place before the experimental volume * protons are considered free streaming to the mesh and those that impact the mesh are removed before the sim starts * A warning should be raised if the mesh is placed withing the front edge of the experimental volume, otherwise an exception should be raised * currently the mesh is added after the creation of the protons, but this will be refactored to be apart of the initialization before the creation of protons * done just needs review * hoping to get in the v0.6.0 release * relativistic boris pusher will test against a relativistic ExB drift * Fitting Thomson Spectra * works pretty well * model to use with LMFIT * functionality is currently slow (not parallelized) * lack of parallelization is due to pickling (of `Particle` class and functionality) * PR could be merged now and the the parallelization will be available one the pickling is fix, since the prallelization is built into the LMFIT functionality * 2nd part to functionality...error estimates & goodness of fit * Need to really review and come to some confidence with the error estimate calculation * method is currently discussed in the [PR's notebook](https://plasmapy--974.org.readthedocs.build/en/974/notebooks/thomson_fitting.html)
