a) N₂H⁺ zero-order moment integrated for all the hyperfine components of the (1–0) transition. Contours start at 3%, increasing in steps of 10% of the peak intensity, 6.01 Jy   beam^-1km s^-1. b) NH₃ (1, 1) zero-order moment (Zhang et al. 2002). Contours start at 10%, increasing in steps of 10% of the peak intensity, 0.202 Jy   beam^-1km s^-1. The synthesized beams, for N₂H⁺ and for NH₃, are shown in the bottom right corner. In both panels the blue cross marks the position of the millimeter source reported in this work. Red crosses: type I (protostars); green crosses: type II (class II objects) from Qiu et al. (2008). Yellow and green tilted crosses are from Chen et al. (2005) and represent Class I luminous protostars with M < 5 M_⊙ and Herbig Ae/Be stars or T Tauri stars, respectively. White crosses are the 5 mm peaks detected with the SMA by Zhang et al. (2007), and the star marks the position of the IRAS 05274 + 3345. The western, eastern, and central cores are also labeled as WC, EC, and CC, respectively. The thick straight black lines represent the direction of outflows A, B, and C (Zhang et al. 2007).
