Notes. The numbers in parentheses represent the 1σ errors. The rms noise of peak intensity is estimated from frequency ranges around each particular transition where the spectrum is apparently free of lines. The error for expansion velocity and LSR velocity is the velocity width of a channel. And the error of integrated intensity given here is the product of the rms noise of peak intensity and the width of the line for about 29 km s-1. Each column represents the following information, Col. (1): molecule name; Col. (2): transition; Col. (3): rest frequency; Col. (4): EU/k, the upper level energy in K; Col. (5): observing date; Col. (6): FWHM beam; Col. (7): peak intensity of main beam temperature; Col. (8): expansion velocity; Col. (9): LSR velocity; Col. (10): integrated intensity. (D) The lines fitted with double peaked profiles are marked with “D”. (F) The lines fitted with flat-topped profiles are marked with “F”. (B) The blended transitions are marked with “B”. (S) Transitions that are smoothed to improve signal to noise ratio are marked with “S”.
