Examples of pixel-by-pixel ro-vibrational diagram towards HH211. Top panel: ro-vibrational diagram in the blueshifted inner jet (R.A.(J2000): 03^h43^m57.469, Dec.(J2000): +32°00′47.″33), where only v = 0 lines (up to S(7)) are detected. In this case, temperature of both components is low and column density is high. Bottom panel: ro-vibrational diagram towards the wing of BS 3 (R.A.(J2000): 03^h43^m59.^s 277, Dec.(J2000): +32°00′35.″13), where both v = 0 and v = 1 lines are detected. In this case, the temperature of both components is high and the column density is low.
