    Dear Serena,
      Thank you for updating the paper and for pointing out the reasons
    why we choose the Tonry et al date. Quoting from the Riess et al.
    paper (section 2)

    "Rest-frame B- and V-band photometry using custom filters was obtained
    for SN 1999Q from observatories around the world. The Hubble Space
    Telescope (HST) monitored the B and V light curves of SN 1999Q from ∼10
    to 35 days after B maximum (rest-frame) using the WFPC2 and the F675W
    and F814W filters in the course of six epochs. Combined, these data
    provide excellent coverage of the rest-frame B and V light curves from a
    few days before to 60 days after B maximum (in the rest frame; A.
    Clocchiatti et al., in preparation)".

      I think it is then reasonable to assume that there is a more
    data on this SNe than just the HST data and the discovery point.

      I will e-mail Alejandro Clocchiatti and ask him directly.

    Regards, Chris.
