This plugin goal is to enable astrophysicists to explore and plot FITS file table and binary table data directly inside Galaxy.

To achieve this goal the plugin main package astrovisjs https://github.com/esg-epfl-apc/astrojsvis relies on :

• fits-reader javascript library https://github.com/esg-epfl-apc/fits-reader
• BokehJS graph library https://docs.bokeh.org/en/latest/docs/user_guide/advanced/bokehjs.html
• D3 graph library https://d3js.org/

All packages are loaded with npm and the plugin is built using webpack

Plugin main features are :

• Explore any FITS file headers
• Explore table and bintable data in table format
• Load local files when dataset relies on external files data
• Multiple files handling
• Automatic column creation based on header data
• Dynamically plot data using D3 or BokehJS from user choices (columns, ranges, error bars, log, .....)
• Error bars support
• Arithmetic columns creation

How to test the changes?

• Instructions for manual testing are as follows:
  1. Load a FITS file containing at least one table or binary table HDU, example file available here https://www.astro.unige.ch/mmoda/gallery/data-products/1e-11451-6141-isgri-light-curve-61 at the very bottom of the page
  2. Launch plugin with selected file
  3. Select file from the "available files" column and use the "Add to plot" button at the bottom to switch it to "current files" column
  4. Select value for X Y axis and error bars if needed (for instance TIME, RATE, ERROR, TIMEDEL)
  5. Plot data using the "Generate" button
