    Hi,

        I have fitted the available cluster SNe with known z using:
    snminuit z band only
    K-corrections from Rollin.
    This is to be compared with David Rubin's fits using Salt.
    What is obvious is that there are 5 clear outliers - presumably not type
    Ia SNe viz B4-Michaela, G3-Brian, F8-Ayako, B3-Isabella, and H3-Elizabeth.
    The overlapping names are O0 and U4 as well as F33, A4 and H5.
    Note that H5-Emma was fitted ommitting one point. This SN occurs in the
    center of a galaxy and may need more careful handling.
