... The internal coordinate system used by arfgen is DET, so if the input coordinate system is EQPOS, POS or TEL, a conversion to DET is performed. ... The conversion from EQPOS to DET in general requires knowledge of the spacecraft attitude. ... It is recommended to use DET coordinates if the mean attitude over the exposure period varies significantly from the start attitude. An intermediate stage of the conversion from equatorial to detector coordinates is via the telescope position (theta, phi). ...

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. ...
