... 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 Python programs offered here result from the development of methodology for processing image data with high precision, in a flexible command line system useful for astronomical and laboratory image processing. ... Alsvid is efficient in robotic and automated or scripted server processing of astronomical images, and also in interactive command line processing for research and visualization. ... In large part it replaces IRAF and IDL when scripted image processing is required. ...

When fits reads a visibility FITS file, it can use one of two schemes for computing the observatory's radial velocity. ... fits assumes that a velocity of a given channel remains constant. ... You can either allow fits to retrieve the needed velocity information from the FITS file, or you can give this information explicitly using the velocity keyword. ...

In Actor Prolog a resident is a special mechanism that helps processes to inspect state of other processes. A resident observes the state of a specified (target) process and if the state of the process changes (for instance, after message handling) it proves a specified predicate of the process. ... Work of the resident. ... Any change of the list of target processes or arguments of resident function results in activation of the resident and repeated collection of information in the target worlds. ...
