HFWHM (Horizontal Full Width Half Maximum)
VFWHM (Vertical Full Width Half Maximum)
A measure of the size of the image, it is defined as the width of the Gaussian fit at half the maximum value. Ideally both should be the same. If different it indicates a problem in collimation, or bad seeing conditions.
RSV (Radial Sum Value)
Radial sum value is a relative measure of star width. As the star gets smaller this number gets bigger.
Peak (Peak Value)
Peak Value is the measure of the brightest pixels in an image. A perfectly focused image will have a higher peak value than an out of focus image. Your goal is to obtain the highest peak value possible.
