... This window allows the user to manually select new sources from the image to be added to the current list of sources. A source is selected by using the mouse to place the cursor at a particular point on the image and then clicking the left mouse-button to store it. By default, the coordinates of the source will be refined by a moments centroiding algorithm, but this can be switched off by unchecking the centroid button. ...

We present ultraviolet, optical, near-infrared, Spitzer mid-infrared, and radio images of 14 radio-selected objects in M33. ... We have detected the majority of cluster candidates in M33 at all wavelengths. ... These results suggest that 11 of the 14 radio-selected objects are optically visible young star clusters with a surrounding H II region, that 2 are background objects, possibly active galactic nuclei (AGNs), and that 1 is a Wolf-Rayet star with a surrounding H II region. ...
