Figure 1b: The black rectangular field of view shown above is expanded to this broad-band K (2.158 microns) image. Select HW cluster sources (Hughes & Wouterlout [1984], Hughes [1988] & Hughes, Cohen & Garrington {1994]) are labeled, as well as a source new to this paper, IRS7.
Figure 2a: Composite of continuum emission images at h (1.644
microns) (green) and
k (2.122) microns (red). HW sources believed to be exciting source candidates have been marked.
Figure 2b: Composite of line emission images of [FeII] (green) and molecular
hydrogen (red). HW sources believed to be exciting source candidates have been marked.
Figure 3a: Extinction: Narrow-band [h-K] color map. Green contours denote 5
sigma detection of the reflection nebula at k (2.122 microns).
Figure 3b: Extinction: [K - L''] Color Map. Green contours outline
10 sigma detection of reflection nebula at L'' (3.81 microns).
Figure 4: Composite of line emission images of [FeII] (green) and molecular hydrogen (red) superimposed with HW ionized hydrogen sources (green contours) and with ammonia emission (yellow contours).
Figure 5: Image of reflection nebula at L'' (3.81 microns). The positions of IRS6 (Lenzen, Hodapp & Solf [1984]), IRS7 and IRS8 (this work) have been labeled as well the position of the 20 micron source. Select HW cluster sources have been marked.
Figure 6: Image of reflection nebula at M' (4.67 microns). Note the
positions of IRS7a and IRS8. Green contours represent the HW
ionized hydrogen sources. The IRS6 sources are those
identified by Lenzen, Hodapp & Solf (1984). IRS6c has no
counterpart in our images; however, Lenzen, Hodapp & Solf may
have detected IRS7a, which has the same magnitude as IRS6c.
