    • Rename file_path_* as file_path in all the export_as_* of the isomclass.

  • utils.kinterp:

    • In get_isoscan, use np.nan in fill_value instead of extrapolate because it is not correct to extrapolate data.

  • INTALLATION.rst:

    • The installation instruction of the master branch are now based on the PyPI package.

  • UPDATE.rst:

    • The update instruction of the master branch are now based on the PyPI package.

1.0.0: 2021/04/11

This is one of the most important release of NavARP, and the project is approaching to a more stable stage. This new version adds very important methods to the NavEntry class which are nicely shown in the now-available examples gallery! In addition, the loading speed has been improved for many text-based files input, and now the krx-MBS format is also supported. Below a list of the main changes divided by modules:

  • navarp_gui.py:

    • Added more colorscale maps;

    • After closing the program, its window size and position are saved (as a file called .navarp inside the user home directory) and they will be used to restore the program the next time it will be opened;

  • utils.navfile:

    • Added support for krx-MBS file format;

    • Added support for ibw file format as saved by Scienta-Omicron SES program;

    • Added support for txt-Scienta file format with 3 dimensions;

    • Added support for igor-pro text file format (saved as .itx or .txt);

    • Loading speed of about x3 faster for txt-based file input (txt from Scienta and MBS, sp2 from Specs);

    • Added set_efermi method to NavEntry to set the efermi of the entry object;

    • Added autoset_efermi method to NavEntry to automatically found the efermi by curve fitting;

    • Added plt_efermi_fit method to NavEntry to show the autoset_efermi results;

    • Added isoscan, isoenergy, isoangle and isok methods in the NavEntry calling the respectively classes in isomclass.

    • Extended dictionary in yaml-file, if loaded overwrite any attribute and efermi and tht_an can be also directly assigned.

  • utils.isomclass (new file):

    • Added IsoScan class with the methods to show in a plot, export as NXdata or Igor-pro text file, postprocessing as interpolation, second derivative and curvature;

    • Added IsoAngle class with the methods to show in a plot, postprocessing as second derivative and curvature;

    • Added IsoK class with the methods to show in a plot, export as NXdata or Igor-pro text file, postprocessing as second derivative and curvature;

  • utils.fermilevel:

    • Added fit procedure without using lmfit, lmfit is no longer required in navarp;
