Introduction

low3 is a program which reads a set of images, and creates a so-called low image. Every pixel in this image contains the lowest-2 value of the corresponding pixel in all the frames.
The low image can be examined (using view) but can also be subtracted from individual images to enhance the peak search procedure.

How it works

low3 reads the images, and of every pixel stores the lowest 3 values. Images of type *low.*, *home.* or *drk.* are ignored.
A low image will be created.
A home image will be created. The pixel values in this image are the frame numbers of the images used to set the value in the low image.

Invocation

low3

You specify the set of images
Answer Yes if you want to create different low images for different scans.

low3 wildimages yes/no
Note, you have to escape the * in wildimages on the commandline.
