4. Recreating Einstein Level One Processing Exposure Masks and Background Maps in
... 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. ...

13. Finding definitions in the source
The HyperNews Linux KHG Discussion Pages . Forum: The Linux Kernel Hackers' Guide . Re : Linux SMP Scheduling (Angela) . Date: Mon, 16 Mar 1998 16:34:54 GMT . From: Felix Rauch < rauch@inf.ethz.ch > . The definition of NO_PROC_ID can be fount by, e.g., the following command: . find . -name "*.[ch]" -print | xargs grep NO_PROC_ID | grep #define . (assuming you are in the Linux-source-directory). This will show that NO_PROC_ID is defined as follows: . #define NO_PROC_ID 0xFF .

... R-band images obtained at 0.8 arcsec seeing conditions have allowed us to separate foreground star from point-like extragalactic source and estimate their brightness separately. ... To study the nature and properties of the source, we observed it under high spatial resolution. ... CONCLUSION RTT150 optical observations with sub-arcsecond seeing and low resolution spectra confirm the hypothesis of superposition of a radio source onto a `normal' F/G galactic star proposed by [1]. ...
