Next: Summary Up: The Second EGRET Catalog Previous: Upper Limits for . In regions of the sky where two or more sources have overlapping point spread functions, it is often difficult to resolve the number of sources and their locations. ... As an example, Nolan et al.(1995) list a source 0445+62 at l = 146.89 , b = 10.65 , with a = 4.0 and a source 0500+59 at l = 150.52 , b = 10.25 , with a = 4.2. ... Both of these sources lie close to the threshold adopted for this catalog. ... 1995). ...

... Concurrent Engineering (CE) is a comparatively new design methodology, which enhances productivity and leads to better overall designs. ... In the development of a product, there are many ``downstream'' aspects to be considered. ... These aspects represent different phases in the product's life-cycle. ... Another advantage of CE is that, while knowledge is being built up about the design of the product, additional knowledge is being acquired about the other aspects of its life-cycle. ...

... specadd creates a multiple X-ray spectrum FITS file by stacking or putting together (``adding'') two single spectrum files. ... This type of spectral files is particularly useful when the user wants to simultaneously analyse different observations of the same object carried out with the same instrument or with different instruments. ... The Data extension for a multiple spectral dataset stores one single spectrum per row, instead of one channel per row as it is the case of single spectrum files. ...

... We study ergodic properties of random maps defined as collections of nonsingular maps $f_1,\dots,f_w$ from a compact metric space $(X,\rho)$ into itself taken with probabilities $p_1,\dots,p_w$ ($\sum_i^wp_i=1$) and considered as Markov processes on $X$. ... In the first situation, when the random map is expanding on average, we mainly follow ideas borrowed from the theory of piecewise expanding maps and the corresponding Banach space is a version of the space of functions of bounded variation on $X...
