摘要：

We present spectral data from 152 observations of 17 comets obtained with an Intensified Dissector Scanner spectrograph at McDonald Observatory. We present the details of the observations and reduction of these data to production rates. These production rates are then analyzed to show that comets seem to be reasonably homogeneous as a group. The ratios of production rates remain constant with activity level and with heliocentric distance, with the exception of Q(NH2)/Q(CN), which shows a heliocentric distance dependence. © 1992.
