TL;DR: In this paper, NGC 6334 has been mapped with a 40-250 µm photometer with 1' resolution and six sources of far-infrared radiation have been detected.
Abstract: NGC 6334 has been mapped with a 40--250 ..mu..m photometer with 1' resolution. Six sources of far-infrared radiation have been detected. The second-strongest source was not detected in an earlier variable far-infrared source. The new source, located at the position of OH and H/sub 2/O maser sources, is extended (0'.7 FEHM) and has a bolometric luminosity of 1.9 x 10/sup 5/ L/sub sun/ and many represent a hitherto unobserved transient stage of protostellar collapse.

TL;DR: The second-strongest source was not detected in an earlier (2.7 years) 40-350 micron survey of the same region, interpreted as a variable far-infrared source as mentioned in this paper.
Abstract: NGC 6334 has been mapped with a 40-250 micron photometer with 1 arcmin resolution. Six sources of far-infrared radiation have been detected. The second-strongest source was not detected in an earlier (2.7 years) 40-350 micron survey of the same region. This source is interpreted as a variable far-infrared source. The new source, located at the position of OH and H2O maser sources, is extended (0.7 arcmin FWHM) and has a bolometric luminosity of 190,000 solar luminosities and may represent a hitherto unobserved transient stage of protostellar collapse.

TL;DR: In this article, radio and far-infrared maps of M17 are presented with an angular resolution of about 15 arcmin, each map has three distinct maxima, two of which agree in position with the corresponding maxima on the radio map.
Abstract: New 35-cm radio and 69-micron far-infrared maps of M17, both made with an angular resolution of about 15 arcmin, are presented Each map has three distinct maxima Two of the maxima on the far-IR map agree in position with the corresponding maxima on the radio map However, the positions of the brightest peak in the radio and far-infrared maps, located in the SW part of M17, differ by 46 + or - 22 s in right ascension and +44 + or - 20 sec in declination, with the far-infrared peak lying between the radio peak and the dense molecular cloud southwest of the H II region It is believed that the positional offset of the radio and far-infrared peak is physically significant The origin of the far-infrared radiation appears to be thermal emission from dust at the interface of the ionized gas and molecular cloud This interface region is probably heated by radiation from the H II region
