The upper text field has the same function as the "Max"−field in the mar345−Colors windo

When pressing the center mouse button in the image area, the x,y−coordinate, intensity an

pper right corner:
When pressing the "Integrate" button in the "Options" submenu (see 4.2.2) the followin
information is displayed: number of pixels in x and y, maximum, minimum and averag
intensity, sum of pixel intensities, standard deviation of intensities, average background an
mean intensity over background (all relative to the pixels displayed in the Image Area). Th
background is calculated from a histogram of intensities of a box of 50x50 pixels around th
center of the zoomed area. Pixel values > 1000 are not included in the histogram. This optio
works for zoom factors >= 1.0 only.
