Stream analysis parameter reference

Show isoline image switch the image format to isoline display. In color mode, this can be used for ADC tuning.
Autodetect planet if active, plugin tries to detect the planet in the ROI. Evidently, this option must be active for live stacking ans tream analysis.
In theory, stacking and other features work also if no planet image can be detected in the ROI, but in the current state, the module is not yet prepared for these cases.
Low det. threshhold specifies the brightness (relative to the actual maximum, in percent) which should trigger planet detection. Might be in need of adjustment to special circumstances, e.g. for daylight observation, or other low contrast situations. The low threshhold is printed in the graph image with a green line. So one has a visual feedback for judging if the current setting is appropriate. The value strongly influences the diameter of the detected shape. So it should remain constant during focus finding based on the printed analysis data and of course also during stacking.
High det. threshold This value is used to calculate the mentioned 'step-sharpness' of the intensity curve.
Vertical cross section position gives the relative position for which the horizontal cross section plot is produced. The value is interpreted relative to the lower rim of the autodetected planet shape, so the the default setting of 50% means a cross section through the (vertical) center.
