... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...

... Animation . Arrow . ... I created the first animation by running Script-Fu / Animators / Fire on the head of an arrow. ... I merged the animation with the background image, and specified a final X offset of -128 (the background is 128 pixels wide). This results in an animation with a nice moving background. Note that you can also use a background that is wider than the image, as long as you specify the width of the background for the final X offset if you want the final animation to loop. ...
