... 2010 February 15 . Cassini Spacecraft Crosses Saturn's Ring Plane . ... Later that century, it became understood that Saturn 's unusual protrusions were rings and that when the Earth crosses the ring plane , the edge-on rings will appear to disappear. ... In modern times, the robot Cassini spacecraft orbiting Saturn now also crosses Saturn's ring plane. ... Saturn's thin ring plane appears in blue, bands and clouds in Saturn's upper atmosphere appear in gold. ... About APOD | ...

Next: Sky Subtraction Up: Construction of Flat Previous: Standard construction . For a number of projects where very deep integrations and accurate flat fields are required, and the targets are point sources or much smaller than the frame size, the sky background itself can be used to calculate the flat field. ... Use STATISTICS/IMAGE to calculate the image median, and COMPUTE/IMAGE to divide by this to get the normalised flat field. ...

Target Acquisition Reference Information . Figure 7.1 on page 88 shows mean predicted count rates as a function of (B - V) 0 color for the four acquisition mirrors. Also shown are the fits to the predicted count rates for different amounts of reddening. ... You can estimate target acquisition count rates using the plots instead of Table 7.1 on page 92 : . ... Read from the Figures (depending on the mirror used) the predicted count rate. ...

... This calibration approach is recommended when dealing with high frequency data from the old ATCA correlator, especially at 3mm wavelengths. ... The approach described here exploits the dual frequency bands that were available with the old correlator. ...
