14. AdelePlunkettAstro
... This is the truly fun part, observing molecular and atomic gas in star-forming regions with a variety of telescopes. Depending on the temperature and density of the gas, different observations are necessary to study the components of star-forming regions. Because stars form in cool gaseous regions, I most often use radio and sub-mm observations, but I also look for opportunities to make complementary observations using infrared and optical telescopes. ...

19. The contour method of calculating source region shape
... 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. ...
