SAOtng can associate names with region markers in order to aid users in remembering the significance of the region. ... By default, marker regions that you create in SAOtng are defined to be either "source" regions or "background" regions and are colored green and red, respectively. ... This type name is controlled by the "Set Type (and Color)" option in the marker menu (activated using the right mouse button within a region). ... Colors can be associated with names for regions. ...

... WFPC2 Home . ... Bright stars near the WFPC2 field of view can cause various artifacts to appear in science images. ... When writing Phase II proposals, observers will sometimes attempt to avoid bright stars by placing them in the un-imaged "L" shaped region adjacent to CCD PC1, or in the region just outside the nominal field of view. ... In both cases the optics can image this light back onto the CCD's. Bright stars must be placed at least 10 arcseconds outside the field to avoid artifacts. ...

... Values have been scaled arbitrarily. High ratios are shown in blue, corresponding to blue colors, and low ratios are shown in red, corresponding to red colors. ... Noise combined with background subtraction difficulties in the lower left quadrant of the WISP1 data (see Fig. \ref{Fig:wisp_snr_mskd}) make colors in this area very unreliable. ... The values shown here are typically a factor of ~3 less than those calculated for the Schmidt data, shown in Figure \ref{Fig:bj_alpha}. ...

. This image from the Smithsonian's Submillimeter Array maps the projected density of molecular gas in the central 30 light-years of W49A. Brighter colors mark denser regions. The brightest region at the image center is less than three light-years across, yet it contains about 50,000 Suns' worth of molecular gas.

... Most of the time large telescopes are collecting light for a spectrograph, which spreads the light out into a rainbow. ... Atoms in the cool outer layers of a star absorb light coming from the hotter regions within, producing dark absorption lines across the spectrum. ... And astronomers do not actually use color film to take a color picture of the spectrum, for several reasons: . ... Color film does a very poor job of representing the continuous range of colors in a spectrum. ... Tutorial: Part 1 |...

... Ignacio Ugarte Urra's PhD thesis topic is the investigation of coronal bright points. In his first paper (in collaboration with Gerry Doyle and Maria Madjarska) he investigated the formation, evolution and decay of a coronal bright point via a spectroscopic analysis of its transition region counterpart and the evolution of the underlying magnetic bipole during 3 days of almost continuous observations. ... In general the bright point has a radiance 4 times higher than that of the network. ...

... 11 Yellow-Green (78% transmission): Contrasts well with the red and blue characteristics of surface features on Jupiter and Saturn. ... 82A Light Blue (73% transmission): Useful on the Moon, Mars, Jupiter, and Saturn, this subtle pale blue filter enhances areas of low contrast while avoiding significant reduction of overall image brightness. ...

... 1994: . Deep CCD images of the bright gamma-ray bursts GRB790418 and GRB790613 localization regions were obtained for the first time. In both cases, a faint blue star-like object (V = 24.5 m , BV m ) was detected within the region of localization of gamma-ray bursts. ... Based on sixty daily instantaneous spectra of the object SS433, obtained on the RATAN-600 in April-May 1994, we traced its variability in four very powerful flares at five frequencies. ...

... Meta Index / Home Page / Description / Specifying source region shapes . When radiusstyle =`contour', the task calculates the source region shape as an elliptical locus which approximates the contour of the PSF at a given flux value. ... Clearly, in order to calculate the shape of such a flux contour, it is necessary firstly to normalize the PSF to the source brightness and secondly to determine the flux level (in `brightness' units per pixel) at which to find the contour. ...

... POLAR , . ... The UT (hours) is shown along the X-axis. Range of X-axis corresponds to the time-interval considered. ... For each spacecraft its own color and line (parallel to the X-axis) are used as follows: . ... On the polar diagram the coordinates of each SC is shown by its own color and regions symbol. ... For more information about SC coordinates on the considered time interval the ASCII files are available (by pushing the colored buttons nearby of the plot). ...

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...
