Treffer: NASA-Planetary-Science/rss_ringoccs: rss_ringoccs v1.0

Release Notes rss_ringoccs Version 1.0 Release date: 2018 September 30 Known Issues and Limitations rss_ringoccs implements effective radial resolution as defined in Marouf, Tyler, and Rosen 1986 (MTR86, Icarus 68, 120-166) eq. 19, using a Kaiser-Bessel alpha=2.5 window function. In contrast, Marouf et al.'s diffraction-reconstructed profiles on the PDS Ring-Moon Systems Node adopt the shortest resolvable wavelength as the resolution metric. Its inverse is the highest spatial frequency preserved in the data. The latter is 1 cycle/km for the 1 km resolution of Marouf's reconstructed profiles. The value corresponds to ~750 m processing resolution as defined in MTR86. The bandwidth of the lowpass filter in the final stage of the data processing chain determines such frequency and is selected to achieve the desired resolution. Workaroud: In order to produce the best match to the RSS diffraction-reconstructed ring profiles on the PDS, specify in rss_ringoccs a desired resolution 0.75 times that given in the PDS files. Power and frequency calibration GUIs give the following error message under some versions of Python on MacOS systems: -[NSApplication _setup:]: unrecognized selector sent to instance *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSApplication _setup:]: unrecognized selector sent to instance' Workaround: Use Linux operating system, and post an Issue on the Github page for rss_ringoccs Power and frequency calibration GUIs may sometimes not close when users click the "OK" button or the red "X" button. Workaround: Use Linux operating system, and post an Issue on the Github page for rss_ringoccs Planned Augmentations Include calculation of threshold optical depth Detailed tutorials to demonstrate the use of the software Runnable scripts to perform push-button diffraction correction, starting either from raw RSS files or from Essam Marouf's (or our) PDS-style geometry, calibration, and diffraction-limited profiles, at any desired resolution (consistent with the ...
