... User Guide ] Task: imstat Purpose: calculate and plot map statistics Categories: map analysis IMSTAT calculates statistics for images. ... Statistics can be found for profiles or planes, specified using the axes keyword. The data can be converted to Kelvin, by using 'options=tb' and the beam keyword. ... The options keyword gives control over the plot. ... An alternative title can be put on the plot by options=title. ... Key: in Standard keyword in. ... Key: region Standard keyword region. ...

... Let us assume to begin with that there is no source at a given location, only background. Let us calculate the probability that the observed counts at that location are due solely to background. ... The routines described in the present section are designed to take as arguments the probability cutoff (actually a cutoff in likelihood is used) and the background, or expectation value for the counts, and use them to calculate the minimum value of source counts which is detectable at those levels. ...

... 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. ...

. This diagram shows a small table with three transparent cells and illustrates how their final background is determined. The table consists of two rows. Four (labeled) cells lie in the first row, but the second cell spans the first and second row. The first, third, and fourth cells of the second row are "empty". Each non-empty cell has a red background and a double black border. Each empty cell has the table's background color (specified as #ff0) as its own. Return to image.
