A note on infrared standard stars During the preparation of the infrared spectral atlas for early typestars, a large number of MK standards was observed in the lambda lambda8400-8800{ Angstroms} region. A list of eighteen standards is givenwhich present some degree of inconsistency between the infrared and theMK type. It is suggested to modify the list of MK standards, excludingthe PI's, so that the list can also be used for the infrared spectralregion. This research was completed before the untimely death ofMercedes Jaschek, who should have figured as the principal author.
