Next: Echelle Reduction Up: No Title Previous: CCD-Commands Summary . The reduction of CES spectra is, especially for point sources, very straightforward, and the general instructions given in Chapter 6 for the standard reduction of spectra are fully adequate. ... As far as the data reduction goes, the main difference between Reticon and CCD is the data format. Since the Reticon is a one-dimensional array, no attention has to (can) be paid to the extraction of the object spectra. ...

To: file From: Jon Hagen Date: 12-22-00 Subject: Azimuth (or other axis) Encoder calibration When an encoder assembly (pinion gear, arbor, flex coupling, and encoder) has been removed and repaired, the encoder position must be recalibrated (reset to its standard position). The most obvious procedure is as follows: Procedure I Move the azimuth arm to a known "cal" position, identified by a pair of scribe marks or other prearranged hardware pointers. Suppose the cal position is 360.000 degrees. ...

... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...
