Fig. 7
Line width as observed throughout the cloud. The FWHMs were derived from a 2nd moment map of the line emission. Broader profiles appear toward the center (>10 km s-1), where the three infrared sources are located, and narrower toward the ionization front (<5 kms-1). The FWHM that characterizes the gas that surrounds the protostars varies between ~5−10 kms-1.
