... 640W A survey of ultracompact (UC) Hii regions has been carried out by searching for 6.669-GHz methanol maser emission from a sample of 535 IRAS-selected candidates. A total of 201 candidates exhibit methanol emission. These sources have been used, in conjunction with previously identified UC Hii regions, to provide a base for further studies of such regions. ... Methanol maser and/or radio continuum emission is found in 364 cases towards IRAS-selected regions. ...

... This example shows the Interference removal for the Baker Electron Density data (Qihou Zhou). ... The Arecibo ISR can measure velocities to an accuracy within 1 m/s for an integration time of 30 second in the D-region. ... The Arecibo ISR can measure the neutral winds and temperature in the E-region. ... We are working on to get the ion neutral collision frequency as well. ... The other parameters that we regularly measure include electron temperature, vector ion drift, light ion contents etc. ...

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. ...
