The cyano radical (CN) is a key molecule across many different factions of astronomy and chemistry. Accurate, empirical rovibronic energy levels with uncertainties are determined for 8 doublet states of CN using the Marvel{} (Measured Active Rotational-Vibrational Energy Levels) algorithm. otrans{} transitions were validated from osources{} different published sources to generate oenergy{} spin-rovibronic energy levels. The empirical energy levels obtained from the Marvel{} analysis are compared to current energy levels from the Mollist{} line list. The Mollist{} transition frequencies are updated with Marvel{} energy level data which brings the frequencies obtained through experimental data up to alert{77.3%} from the original 11.3%, with 92.6% of the transitions with intensities over 10$^{-23}$ cm/molecule at 1000 K now known from experimental data. At 2000 K, 100.0% of the partition function is recovered using only Marvel{} energy levels, while 98.2% is still recovered at 5000 K.
