Constructor Detail

VideoGuider

public VideoGuider(Map<String,String> prop)

Constructs a new adapter helper, defaulting all properties.

Method Detail

getRaDeCenter

protected Vector2D getRaDeCenter()

We guide directly on the object, thus we return the first object in the field of view.

Specified by:

getRaDeCenter in class AbstractStarGuider

getPinhole

protected Point2D getPinhole()

Returns the position of the pinhole, which is now further detailed by a functional dependency of the pinhole x/y on the video guider by the focus and the telescope altitude. We determined that using the exe.FocusSpindleFit an images taken with ThAr lamp on and positioning the sledge at different focus positions using the script focusadapter.sh on archive.
The results for different elevations can be found on chianti in /work1/wooz/stella/pinhole-adapter2/, especially the files fit60000a.agr, fit60000a.log (func2.dat, derived from sesh??a.drift). The results in fit60000.agr (func.dat) have been obtained with blindly using focus values from 40000-69000.
