... A new IRAF task has been developed that automatically identifies linear (line-like) features in an image or set of images. ... In order to automatically detect linear features, the first step is to select pixels in the image (Fig. 1 , left panel) that fall within a given data value range. ... Another aspect of extended linear features is that the image space pixels that describe them are in some way adjacent to one another and have a minimum and maximum length. ...

... We present a comparison of the surface density of young stars (неБ‹†) and dust surface density (неdust) across NGC 346 (N66) in 115 independent pixels of 6 ц— 6 pc2. ... We convert неdust to gas surface density (неgas) and неБ‹† to star formation rate (SFR) surface densities (неSFR), using simple assumptions for the gas-to-dust mass ratio and the duration of star formation. ... On small scales the неSFR derived using Hн± systematically underestimates the count-based неSFR, by up to a factor of 10. ...

The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...

... It will automatically identify any fuzzballs in this picture. It will then randomly select one of these fuzzballs, and get a spectrum of it. ... A declination of 90 will find you a fuzzball directly overhead. ... Once you pick a region, press the "find and measure" button and your automatic telescope will search for a fuzzball near these coordinates. ... If you hit the "find and measure" button repeatedly at the same coordinates, the telescope will keep on finding new fuzzballs near this position. ...
