Methanol absorption (magenta contours, integrated from V_LSR = −13.9 to 0.5 km s⁻¹) seen in D-array data, overlaid on extended continuum emission toward DR21 (blue scale and contours) as seen in our VLA D+B array configuration map. The nth contour is at , where: S_max = 1.2 Jy beam⁻¹, n = 1, 3, 5..., and p is equal to 0.4% for the radio continuum; and n = 0, 1, 2..., S_max = −3.2 Jy beam⁻¹ km s⁻¹, and p = 16% for the methanol absorption. The synthesized beams (4″ × 4″ for the VLA D+B map and 14.″4 × 10.″7 at PA = −84.1° for the D-configuration map) are shown at the bottom corner. The white stars mark the positions of Class I methanol masers observed in the 95 GHz 8₁ − 7₀   A⁺ line (Plambeck & Menten 1990). The orange stars are 44 GHz 7₀−6₁ A⁺ methanol masers (Kurtz et al. 2004).
