Next: Displaying Images Up: Spectral Line Data Reduction Previous: Computation . A few comments are in order when using the imaging task, invert , to create spectral cubes (more information on invert can be found in Chapter 13 ): . To conserve space, invert produces a single beam dataset for all planes of a cube. ... That is, invert usually insists that no channels of a spectrum are flagged before that spectrum can be used for imaging. ... The slop keyword takes two values. ... VELSW . ...

Next: Introduction . ... This work reports results on intercomparison of image restoration algorithms, when used in the specific context of stellar fields imaged by the HST WFPC. Properties as fidelity to the original image and photometric linearity, as well as computation performance, were evaluated. Keywords: image restoration, deconvolution, image processing, HST, photometry . Introduction . ... Results . ... Fri Apr 15 16:19:48 EDT 1994 ...

... The TRACE images may be used without restrictions in publications of any kind. ... These two images, taken on 18 November 2000 at 15:54UT and 16:11UT, respectively, show such an event: the red circle in the image to the left shows a region where many loops are cooling, with bright loop tops (the intensity scales with the square root of the image to reduce the dynamic range). ...

... Up: Algorithms . ... The imaging problem can be described as an optimizing problem in mathematics. ... Computer simulations of rotating modulation collimator imaging show that the quality of images from this method is better than that from the traditional cross-correlation method. ... The imaging problem is: . ... The results show that this algorithm can be used in the imaging problem and usually results in a better image than that obtained from a traditional method such as cross-correlation. ...

... As an experiment, I made some three-color images of Messier 42, more commonly known as the Great Nebula of Orion. ... green enhanced . ... halfsize or fullsize . ... Each image is a ``true color'' composite of three monochromatic images, in which the red, green, and blue intensities each correspond to the intensity of one of the original images. ... The HST image is assembled from different filters than mine: red is Nitrogen [II] at 6583 , green is H-alpha at 6563 , and blue is O [III] at 5007 . ...

This WWW form allows the user simplified access to images produced by the NRAO/VLA Sky Survey (NVSS). This service determines which NVSS image is desired based on a celestial position and returns either the image directly or a Web page with a link to the file. ...

... Image extraction is enabled by setting the name of the output file using the parameter imageset . The name of the columns to use for the and axes of the image are set using the parameters xcolumn and ycolumn . ... If no WCS information is available for a column, then the CTYPE keyword for this axis of the image is set to the name of the column, and the other WCS keywords are set to reflect the range and binning of this column, as is done for SPEC* keywords in spectral extraction. ...
