Integrated ¹²CO antenna temperature map of MBM 3 of the primary cloud between -10.9 and -4.9 km s^-1 (gray scale), and integrated ¹²CO antenna temperature of the outlier cloud between -2.5 and 1.2 km s^-1 (pale blue contours). The bottom panel shows ¹²CO (thick black line) and ¹³CO (thin red line) averaged spectrum over the whole cloud. The highest peak traces the gas linked with the primary cloud, while the other peak traces the outlier cloud, which shows virtually no ¹³CO emission. The ¹³CO spectrum is multiplied by a factor of nine for clarity.
