Notes. Observed HCS+ lines in the frequency range of the Orion KL survey. Column 1 gives the observed (centroid) radial velocities, Col. 2 the peak line temperature, Col. 3 the integrated line intensity, Col. 4 the quantum numbers, Col. 5 the assumed rest frequencies, Col. 6 the energy of the upper level, and Col. 7 the line strength.
