FViewer: Fits image and table viewer
FViewer is HEASARC's tool for viewing FITS images and tables. It provides a user-friendly, browser-based interface for exploring and analyzing FITS files. It replaces the classic FV tool, which is no longer being maintained.
FViewer is an open source, modern, fast, and interactive viewer for astronomical FITS files and catalogs. If you have ever used traditional desktop tools like ds9, js9 or fv, FViewer may feel familiar, but with a major upgrade: it runs directly in your web browser and connects seamlessly to your Python code. FViewer started primarily as a replacement for the HEASARC's fv tool, but quickly evolved to more features.
The tool is available on github. The full documentation is available on the documentation site.
The tool can be installed locally with: pip install fviewer.
The demo below shows the tool in action. Note that features such as catalog querying
and python interaction are available when you install the full version with pip.
