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. ...

... User Guide ] Key: offset A number of Miriad tasks either take or return celestial coordinates as offsets from some reference position -- invariably the observing center or the reference pixel. ... Offset celestial coordinates are always given in arcseconds on the sky. The offset, (x,y), is related to a true sky coordinate, (RA,DEC), by x = (RA - RA0) * cos(DEC0) y = DEC - DEC0 (These equations should be viewed as a definition, rather than a small angle approximation). ...

On,off position switching is done to remove standing waves from the resulting spectra. ... 1,5,10,20,25,50,100 samples corresponding to great circle angular offsets of .004,.02,.04,.07,.09,.18, and .35 degrees. ... Page 1: rms vs great circle offset. ... Page 2: rms vs little circle offset. ... The rms increase correlates better with great rather than little circle offsets. the 1 usec standing wave starts to be seen in the .07 degree offsets. a .9 usec standing wave is seen at .35 degrees offset. ...

... This paper describes a simple technique that cancels the DC offsets often found in Hubble Space Telescope's calibrated NICMOS images. ... Hubble Space Telescope NICMOS images often show quadrants with a slight mismatch in DC offset levels after the calibration process. ... Figure 1: NICMOS image showing DC offsets between quadrants. ... Figure: Same image depicted in Fig. 1 after being processed by the DC offset removal algorithm. ...

Any type of filtering can be applied to the input qpoe file, including region filtering. In addition, the size of the output event record can be different from the size of the input event record. ...
