Distribution of blueshifted outflow from the Spitzer source. (a) The blue color scale image and blue contours show images of velocity-integrated intensity of ¹²CO (J = 3–2) with a velocity range of 0.0–4.0 km⁻¹. The lowest contour and subsequent contour step are 0.03 Jy beam⁻¹ km s⁻¹. Black contours show the image of 0.87 mm dust continuum emission, as in Figure 1. The angular resolution of the ¹²CO (J = 3–2) is given by the black ellipse in the lower left corner of the bottom left panel, 0.″73 × 0.″33. The red plus sign represents the position of the Spitzer source. Green contours show images of velocity-integrated intensity of HCO⁺ (J = 3–2) with a range of 0.0–4.0 km⁻¹. (b) Blue and black profiles show averaged spectra over the regions inside the blue lowest contour and a circle with a radius of 9.″0 at the center position of (﹩{\alpha }_{J2000.0}﹩, ﹩{\delta }_{J2000.0}﹩) = (4^h28^m38.ˢ80, +26°51′38.″3), respectively. The blue dashed line shows the velocity range for blue contours in panel (a).
