GRISView is a visualization and analysis tool to work with GRIS/GREGOR calibrated datasets as
distributed by SDC website. It is written in Python with GUI made using Qt cross-platform framework.

GRISView features include:

• Quick panning and zooming of maps and spectra
• Multiple POI (point-of-interest) and ROI (rectangle-of-interest) for easy inspection and comparison of spectral profiles across the map
• Distance measurement between map points in different units
• Interactive image color bars to show histograms, adjust image contrast, set and customize color schemes
• Building profile plots along selected directions
• Generating contours for maps using color schemes and interactive levels adjustment
• Browsing spectra using the mouse and keyboard, quick navigation through spectral lines and markers
• Relative wavelength scale for quick difference evaluation at selected cursor position
• Showing input and derived Stokes parameter plots with Quiet Sun continuum normalization
• Support for single-map observations and multi-map time-series, including IFU and spectroscopic mode data
• Viewing observation file headers
• Exporting spectral and map plot view area as images
• Saving and restoring working sessions
