setirotate automatically spawns the SETI@Home commandline client, rotating it through work units in a work unit cache. You can configure the number of work units to store, the number of processes to run simultaneously, the number of simultaneous result-upload/workunit-download transfers, the time interval within which its allowed to perform said transfers, and the timeout interval for when a transfer fails. It will immediately start working on a work unit when the previous one finishes, while uploading the newly finished result (if the upload interval permits) in parallel. It strives to always keep something running.
PAPFIP (Python And PGPLOT-based FITS Image Plotter) is a FITS image plotter based on the Python bindings to the pgplot graphics library. It is intended as a non-interactive (command line or script-driven) astronomical image plotter intended for the automated or repeated production of finalized publication-quality Postscipt files, rather than a method of inspecting or visualizing the data.
NOVAS (Naval Observatory Vector Astrometry Subroutines) is an integrated package of subroutines for the computation of a wide variety of common astrometric quantities and transformations. It can provide the instantaneous coordinates (apparent, topocentric, or astrometric place) of any star or planet, and also provides general astrometric utility transformations, such as those for precession, nutation, aberration, parallax, etc. It is useful for data reduction programs, telescope control systems, and simulations.
