... 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. ...

The File System . This section describes how you can create new files, copy existing files, and delete obsolete files. ... RENAME to change the name of a file. ... Files can be created in several ways: text can be entered from the keyboard via the CREATE command, an editor can create a file, as can a running program, and files can be copied from other directories. ... To delete obsolete files, use the DELETE command followed by a file name or file name template (wildcards). ...

. To place files under the control of SCCS use the command: sccs create filename(s) . For each filename given as an argument sccs create does the following: . filename is moved to ,filename . a history file s. filename is created in the SCCS subdirectory . a "read only" copy of the initial version of the file is made by sccs get . You can use the ls command to check that the history files have been created. ls SCCS . Now you can remove the ,filename files: rm ,* .
