... 2005 June 6 . Saturn: Dirty Rings and a Clean Moon . Credit: Cassini Imaging Team , SSI , JPL , ESA , NASA . Explanation: Eating surface ice from Enceladus might be healthier than eating ice from Saturn's rings -- it certainly appears cleaner. From their apparent densities and reflectance properties, both the rings of Saturn and its shiniest moon, Enceladus , are thought to be composed predominantly of water ice . ... About APOD | ...

... User Guide ] Task: clean Purpose: Apply Hogbom, Clark or Steer CLEAN algorithm to a map Categories: deconvolution CLEAN is a MIRIAD task that performs a hybrid Hogbom/Clark/Steer Clean algorithm, which takes a dirty map and beam, and produces an output map which consists of the Clean components. This output can be input to SELFCAL to self-calibrate visibilities, or input to RESTOR to produce a "clean" image. ... Key: map The input dirty map, which should have units of Jy/beam. No default. ...
