Opacity and Phase of Saturn Rings Data


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1984-05-22 to 1984-05-22


These experimenter-supplied data are on magnetic tape and consist of X- and S-band opacity and phase of Saturn's rings as derived from the Radio Occultation Experiment on Voyager 1. The data have been processed to improve their spatial resolution. An inversion filter has been used to derive an approximation to the true profile of opacity and phase by taking into account the diffraction effects of the rings. The data file, File 3 on the tape, contains both pre- and post-inversion data. File 1 on the tape contains a "simulated impulse response" - that is, the data that would be generated by the inversion filter if the ring contained an extremely narrow transparent gap in an otherwise opaque ring. File 2 contains a similar "simulated step response," which illustrates how an infinitely sharp transition from an opaque ring to free space would appear after inversion. The first file on the tape, File 0 (ASCII format), contains documentation of the contents of the tape, including a general description, information on file formats, record formats, number conventions, and a sample program to read the data from the tape.
