TripleSpec Guider Settings

 

 

 

This dialog box is called by pressing the "Settings" button on the Guider area (bottom right corner) of the Guider GUI.

 

 

Settings definitions

 

Guiding Threshold:

����������� Sets the threshold required for the guider to assume there is enough signal to guide. If 5 % of the pixels inside the box area have at least a _threshold_ % value of the peak, then the correction will be sent.Otherwise it will be rejected and an error message will appear on the messages area of the main window ("-34 NO SIGNAL"). Also the "last" LED will be turned off.

 

Seeing Tolerance:

����������� Any correction with a value < Seeing_Tolerance will NOT be sent, assuming they are variation due to seeing and not real corrections.

 

Gain:

����������� This is the "attenuation factor" applied to the calculated correction.This number must be adjusted to avoid overshoot or oscillation on the telescope.

 

Max Correction rate:

����������� Sets the maximum rate for the corrections, in seconds.Any correction calculated before _max_ seconds will not be sent.

 

Telescope Move Rate:

����������� Sets the speed at which the telescope will move when a correction is sent (in arcsecs/sec).

 

Algorithm:

����������� Defineswhich algorithm will be used for the guiding process: CMASS (Center of Mass) or QUAD (four quadrant weighting). CMASS is the algorithm used by default.

Xcenter/Ycenter:

����������� Sets a specific position (pixel-precision) for the center of the guide box.When the box is moved with the mouse this value gets updated and vice/versa.

 

Xoff/Yoff:

����������� Sends an offset for the guide box.The offset can be specified in pixels or in arcsecs.If arcsecs are used, Xoff and Yoff become RA and DEC.

 

Xsize:

����������� Sets the size of the guidebox at pixel-precision. This can be specified in arcsecs or pixels.
