2MASS K_s-band image of the region associated with IRAS 05345+3157 (colour scale). The white contour represents the 6% level of the maximum (~0.039 Jy beam^-1 km s^-1) of the NH₃ (1, 1) zero-th order moment map. The yellow circle centred roughly at Dec +32°00′20′′ pinpoints the location of the 4.5 μm source discussed in the text (Sect. 3.2.1). The position error of the IRAS source is indicated by the grey ellipse.
