... 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. ...

Keep the size of the tarfile to a minimum by excluding files that can be recreated from files contained in the tarfile. Examples are: .o (object) files that can be recreated by compiling the program source code.dvi files produced by processing TeX and LaTeX source files.ps (postscript) files generated by drawing and publishing packages. After you have created a tarfile, you can then reduce its size by using the compress command. ... This will create a file called project.tar.Z . ...
