pyvista is a package for the inspection, reduction, and analysis of astronomical data. It includes a native Python display tool, tv, that is modeled after the original xvista display tool.

Much of the package is under some level of development, but includes modules for:

• image display (tv)
• image reduction (imred)
• spectral analysis (spectra) : tracing, wavelength calibration, fluxing
• observation planning (skycalc) : wrappers around astroplan
• exposure time calculation tools (etc)
• stellar photometry (stars) : wrappers around photutils)
• image manipulation (image) : functions for basic image manipulation, including boxes
• image simulation (simulate)

Some examples, in the form of jupyter notebooks, can be found in the docs/notebooks subdirectory of the distribution, see https://github.com/holtzmanjon/pyvista/tree/main/doc/notebooks
