A number of different choices are possible on WFPC2 in order to approximate the Johnson-Cousins system often used in ground based observing. These choices differ in throughput, wavelength fidelity, color transformability, and cosmetics. The HST science program as a whole benefits if a standard set can be agreed upon by the community for broad band photometry. ... These filters form the basis for the WFPC2 broad band photometric system. ... Space Telescope Science Institute . ...

Magnetic field measurements onboard the Interball Tail spacecraft are carried out by the FM-3I instrument which consists of two flux-gate magnetometers covering two different ranges: [-200, +200] nT and [-1000, +1000] nT. Besides scientific goals, the FM-3I experiment data is used to perform the attitude control of the Interball Tail spacecraft. ... August 22, 1995 . ... October 18, 1995 . Top of the page . ...

NICS (Near Infrared Camera Spectrometer) is the camera/spectrometer that the Infrared Group at Arcetri Observatory is designing and building for the National Telescope Galileo ( TNG, Telescopio Nazionale Galileo ), on behalf of the Italian astronomical community. ... This document is not aimed at providing a detailed description of the various parts of the instrument, the reader will be addressed to specific papers and reports for technical details. ...

TUI supports the following offsets: . Object Arc offset by a given amount on the sky (i.e. along the arc of a great circle). ... Arc offsets are useful for moving a different portion of your object or a different nearby object onto the boresight . ... Object Arc XY this is identical to an Object offset except that it has been rotated to align along the instrument x-y axes. ... This is just like the Calibration XY offset, except that it is typically cleared when you slew to a new object. ...
