Summary0001995: Curvature indication for image inspection
DescriptionAttached a proposed modification for routine procedure Tf_main.MeasureImage in pu_main.pas. This gives an additional estimate for the curvature.

This could be useful for Newton, RC telescope users experimenting with a flattener (distance)

It simple extends the current routine with two new areas, the center 25% of the image and the outer area >75% diameter. The two new calculated median HFD's are compared in ratio. Is the HFD in the outer range twice as large as the center, this indicated by a curvature value of 100%.

Steps To ReproduceUse attached routine.
Additional InformationI used the latest code downloaded this morning. Only the procedure Tf_main.MeasureImage in pu_main.pas has to be replaced.

A new translation keyword was added in U_translation.pas

Note that current tilt indication uses a ":" rather then a "="
