Maps of NH₃ rotational temperature in units of Kelvin (left), the logarithm of the total-NH₃ column density in units of cm⁻² (middle), and the corresponding logarithm of the fractional abundance (right). The reference position is R.A. : 18:14:13.50, DEC. : -17:55:47.0 (J2000). The integration range is 32 to 40 km s⁻¹. Contours are the same as in the left panel of Fig. 6. The limits of the mapped region over significant parts of our map are indicated by gray dashed lines. The half-power beam width is illustrated as a gray filled circle in the lower left corner of each image.
