We describe recent developments in the Ginga package, a open-source astronomical image viewer and toolkit written in python and hosted on Github. The package was introduced to the scientific python community at SciPy 2013 and has received a number of enhancements since then based on user feedback. The talk includes an image mosaicing demo of a wide-field camera exposure with 116 4Kx2K CCDs.
Ginga is an open-source astronomical image viewer and toolkit written in python and hosted on Github. It uses and inter-operates with several key scientific python packages: numpy, scipy, astropy and matplotlib.
In this talk/poster we describe and illustrate recent enhancements to the package since the introductory talk at SciPy 2013, including:
- modular/pluggable interfaces for world coordinate systems, image file I/O and star and image catalogs
- support for rendering into matplotlib figures
- support for image mosaicing
- support for image overlays
- customizable user-interface bindings
- improved documentation
- self contained Mac OS X packages
During the talk we will demonstrate the mosaicing plugin that is being used with several instruments at Subaru Telescope in Hawaii, including the new Hyper Suprime-Cam wide-field camera with 116 separate 4Kx2K CCDs.
The talk/poster may be of interest to anyone developing code in python needing to display scientific image (CCD or CMOS) data and astronomers interested in python-based quick look and analysis tools.
