A VLA SURVEY OF OPTICALLY VISIBLE GALACTIC H-II REGIONS

Radio continuum observations of 109 optically visible Galactic H II regions were obtained with the Very Large Array. Contour plots of the images of those that were well resolved and tables of radio continuum flux density for all detected objects are presented. The measured total flux densities matched well with the results of single-dish surveys and thus it is expected that the problem of missing ''zero-spacing flux'' has not contributed greatly to the morphologies seen in the resulting images. The relative numbers of objects of each morphological type were very similar to the numbers seen in the survey of ultracompact H II regions by Wood & Churchwell (1989) even though the objects in this new survey are on average 50 times larger (in radius) and therefore presumably more evolved.
