Notes. The beam size is 0.14′′ × 0.1′′ for G10.47+0.03 and 0.15′′ × 0.11′′ for SgrB2. The rms on 1 km s^-1 channels is 120 − 150 K. Results of Gaussian fits and lower limits on the optical depth τ and on the column density of hot HCN are given.

^(a)

The continuum flux density is the brightness temperature at the given locations in the line maps (which have a larger beam than the pure continuum maps). To convert from K to mJy/Beam, one has to divide by 53 for G10.47+0.03 and by 45 for SgrB2.

^(b)

Full Width at Half Maximum (FWHM) of the Gaussian.

^(c)

The numbers in parentheses are powers of 10.
