... 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). ...

Set the display of the status bar, tool bar, locator bar, and properties associated with the display of the pointer position in the Locator bar. ... Set fixed point . ... When the fixed point is set, and the display format is (DX, DY), (DIST), or (R, Theta) then give the location relative to the fixed point. ... Set the fixed point to (0.0, 0.0). ... DX, DY] Display the delta in X and Y of the position of the mouse relative to the fixed point, or (0, 0) if no fixed point has been selected. ...

To examine the catalogue table created by the command FIND/ROMAFOT one should use the command ``M'' followed by the sequential position of the object. ... A subframe with the selected star at the center is presented to the user. ... During the examination of the objects passed by FIND/ROMAFOT it often happens that several stars are asked to fit together in the same window and some of these are in the catalogue table. ...

Next: Summary Up: Design Previous: Logical View . The screen design is part of the user interface development, and is a result of the storyboarding described in Section . ... This provides a good overview of how the user interface development had to be broken down to meet the design requirements. The Menu Bar is located at the top of the screen, and provides access to several functions available throughout the design session. ... The Palette of Objects is located in the upper right. ...

Next: Analysis Tools for Nebular Emission Lines . ... Extracting spectra from a large number of NICMOS grism images requires a convenient interactive tool which allows a user to manipulate direct/grism image pairs. ... The direct image is used to locate objects of interest, to find the position of the appropriate spectra in the grism image, to determine the optimal extraction technique to use, and to calibrate the wavelength range of the extracted 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. ...

... CoordConv is written in C++ and Python, using SWIG as the C++ wrapper. ...
