Image Details
Caption: Fig. 4.
NGC 2024 star‐forming region, imaged in 3 mm continuum with the OVRO Millimeter Array (gray scale). All the OVRO data were used to create this image, and the angular resolution is 3﹩\farcs﹩84 × 3﹩\farcs﹩22. The unit gain region of the mosaic encompasses a 2﹩\farcm﹩5 × 2﹩\farcm﹩5 area (solid contour), and the average rms of the residuals within the unit gain contour is ~1.3 mJy. We have labeled the previously detected submillimeter sources FIR 2, 3, 4, 5, and 6 (Mezger et al. 1988) and IRS 2 (Wilson, Mehringer, & Dickel 1995). Also, the horizontal emission regions labeled NCP and SCP correspond spatially to the free‐free emission regions observed in VLA centimeter continuum maps (Crutcher et al. 1986; Gaume, Johnston, & Wilson 1992). While it is difficult to distinguish FIR 4 from NCP in this image, FIR 4 is clearly visible in Fig. 5.
