In using the IRIS - Mariner 9 data an instrumental effect has been identified which, although small enough so that does not effect essentially previous results, yet may be important for future studies. The effect consists in a duplication at twice the frequencies , of the spectral features, reduced to a small intensity of some percent of the real value. The effect is caused by an internal reflection of martian radiation from the entrance window. A possible empirical correction is given.
