skycat 3.1.2+starlink1~b+dfsg-5build4 (arm64 binary) in ubuntu groovy

 The ESO/Starlink Skycat tool combines the image display capabilities
 of the RTD (Real-Time Display) with a set of classes for accessing
 astronomical catalogs locally and over the network using HTTP. The tool
 allows you to view FITS images from files or from the Digitized Sky
 Survey (DSS).
