... GHRS IMAGEs and MAPs are obtained with the focus diodes (see Section on page 80 ) at the ends of the array of main science diodes. ... An IMAGE can only record the light in the 1.74 1.74 arcsec region of the LSA. ... A standard IMAGE will have a pixel spacing of 0.109 arcsec and will cover the entire LSA aperture of 1.74 1.74 arcsec. You may also select pixel spacings of 0.055 or 0.027 arcsec, with proportionately smaller regions of the sky covered in a 16 16 (the default) IMAGE. ...

Permitted Context: %text . ... The <IMG> tag is used to incorporate in-line graphics (typically icons or small graphics) into an HTML document. This element is NOT intended for embedding other HTML text. ... Browsers that cannot display in-line images ignore the IMG element unless it contains the ALT attribute. ... Take values TOP or MIDDLE or BOTTOM, defining whether the top or middle or bottom of the graphic should be aligned with the baseline for the text line in which the IMG element appears. ...

... regionmask region=<table> autosize=no withmaskset=yes maskset=mask.ds . ... regionmask converts a FITS Region extension table to an image mask, either as a FITS image or as an ASCII list of pixels. ... These same parameters also define a clipping rectangle (the origin and extent of the output image), which engages by default. ... image . ... The WCS keywords specify the size and alignment of the pixels and the bounding keywords specify the clipping rectangle of the output image (unless auto-sized). ...

... 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 . ...

... The STECF IRAF layered package impol provides five tasks specifically aimed at reduction of HST imaging polarimetry data for ACS, FOC, NICMOS and WFPC2. ... Reduction of HST polarimetry data and simulation of raw polarimetry images, together with polarization vector plotting, are covered. ... hstpolsim -- Produce simulated polarization input data frames for HST instruments from images of the total signal, the linear polarization and the position angle of the polarization vectors. ...

... 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). ... See also a collection of images related to the Sun, other cool stars, and solar-terrestrial effects . ... Images | ...

Next: An example of Up: Classification of Images Previous: Creation of the . The classification process (command CLASSIFY/IMAGE) tags each frame with one or more character strings supplied by the user that classify the image in a unique way and will be stored into columns of the OST. For instance scientific exposures observed in SUSI using the filter number 639 may be described` with the two strings ``SCI" and ``FILT_639". ... The command CLASSIFY/IMAGE ntt WFIB :OPATH FB&1 . ...
