Go to the previous , next section. SM has some capability for handling image data. You can define an image with the image command, which is analogous to the data command for vectors. As described in the manual, you must first tell SM what sort of image file it is. ... Once you have read in the image, you can contour it with the contour command (first define the contour levels with the levels command), and you can take a slice through it with the set x = image(x,y) command. ...

... All optional images (except the convolvers in inconvolversarray ) must however be of the same dimensions as the inset . ... Optional) inconvolversarray : both this file and inindeximagearray are read when smoothstyle = `withset'. inconvolversarray should contain a cube or 3-dimensional array which is a stack of convolver images. ... Optional) inindeximagearray : both this file and inconvolversarray are read when smoothstyle = `withset'. inindeximagearray should contain a 2-dimensional array. ...

... Quadtrees have a wide range of applications, from graphics to image processing to spatial information systems. ... With the advent of the Guide Star Catalog and other large astronomical source lists, an efficient method of storing and accessing such spatial data is necessary. ... We also discuss how the linear quadtree can aid in the correlation of source positions from different astronomical catalogs and how it can be applied to relational databases. ...

... This chapter describes JavaScript expressions and operators, including assignment, comparison, arithmetic, bitwise, logical, string, and special operators. ... An expression is any valid set of literals, variables, operators, and expressions that evaluates to a single value; the value can be a number, a string, or a logical value. ... Logical: evaluates to true or false . ... A comparison operator compares its operands and returns a logical value based on whether the comparison is true. ... Operator...

... The MROI makes use of optical interferometry, much like COAST . ... As a major collaborator, the Cambridge Astrophysics Group is currently developing some of the mechanisms below, specifically the delay line and the fast tip-tilt system. ... Fringe tracking is used to control the positions of the delay line trolleys to make sure the light beams from the different telescopes in the MROI arrive at the science camera beam combiners in phase so that an interference pattern can be produced. ...
