    Hi Chris,
    c.c.deepnews

    Saul, Greg, Kentaro, Nobunari, Tomoki and I got together tonight
    at Subaru building, and talked the future plan for follow-up obs.
    Since Saul and Greg are leaving Hawaii soon, I made a summary here.
    Though I summarize the plan, I didn't include detailed information
    for HST follow-up plan, which I am not very much familiar with. I
    rather focus on the ground based follow-up plan especially for
    next 1 month. Please tell us how you think about the following plan.

    As Greg sent an e-mail this morning, we will get light curves
    of the following three targets with ACS (5 visits) and NIR photometry
    with NICMOS.

    (A)
     SuF02-012(z=1.3or1.5)
     SuF02-065(z=1.18)
     SuF02-060(z=1.063)

    Among these three, we will take grism spectra of the following
    two SNe.
     SuF02-012: to get redshift using continuum shape at around 1micron
     SuF02-060: to get better S/N sepctrum

    In addition to these three, we want to get light curves and colors
    of the following two high-z targets with HST and with ground based
    telescopes.

    (B)
     SuF02-071(z=0.928)
     SuF02-017(z=1.0)

    The current plan to follow these are

    1)NIR photometry
     SuF02-071(J=23.2-23.7) Nov.15 ISAAC J
     SuF02-017(J=23.3-23.8) Nov.16 CISCO J, Nov.29 ISAAC J

    Here I wrote approximate dates.
    On the Nov.29/30 we want to carry out photometry of
    017 again to get color (with ACS) and NIR light curve.

    2)optical light curve
     SuF02-071 Nov.18(ACS) Nov.27(Suprime-Cam) Dec.6(Suprime-Cam)
     SuF02-017 Nov.27(Suprime-Cam) Dec.28(HST) Dec.6(FORS2, Suprime-Cam)

    071 is in overlapped area of SXDS1 and SXDS5 and exposures with
    Suprime-Cam will be twice compared with 017 which is only in SXDS1.
    (We will follow only SXDS1 and SXDS5 with Suprime-Cam.)
    So if you spend 2-3 hours for 017 with FORS2, that would be very
    nice. Also in case the weather is bad, and we can't do photometry
    with Suprime-Cam, we would like to put more FORS2 time to do
    photometry of these two SNe. FORS2 can probably do deep photometry
    of these two targets after the periods above.

    We also think it would be a good idea to measure J-band color
    at similar redshifts, especially to estimate extinction effects
    using CMAGIC technique. Suprime-Cam will make optical light curve of
    the following SNe. We want to do J-band (I-band in rest frame)
    photometry wiht ISAAC and with CISCO.

    (C)
    SuF02-025(z=0.606) CISCO J
    SuF02-082(z=0.623) CISCO J
    SuF02-001(z=0.57) ISAAC Jshort/ CISCO J
    SuF02-019(z=0.505) ISAAC Jshort

    We want to integrate targets until S/N ~ 20
    (where systematic errors may become important at least for CISCO).

    If we write down the schedule in time sequence,

    Nov.14-19 CISCO J SuF02-017 SuF02-025 SuF02-082 SuF02-001?
    Nov.15-17 ISAAC J SuF02-071 (save time for SuF02-017 on the 29th)
    Nov.18-20 ACS i/z SuF02-071
    Nov.26 FORS2 I SuF02-017 (+ 071?<-- Mauna Kea weather forcast)
    Nov.27-28 Sup-C i' SXDS1 SXDS5
    Nov.28-30 ACS i/z SuF02-017
    Nov.29-30 ISAAC SuF02-017, SuF02-019
    Dec.3 ISAAC SuF02-017, SuF02-019
    Dec.6-7 Sup-C SCDS1, SXDS5
    Dec.6-10 FORS2 SuF02-017 + more (depending on weather)
    Dec.8-12 ISAAC We probably used up the time..
    .... FORS2 SuF02-017, SuF02-071 if time available

    We need close contact between you and us, telling each other
    which targets we finished, how the weather look like, etc.

    For CISCO observations, Kentaro Motohara is in charge,
    since M.Doi is leaving Hawaii for Japan on the 16th.
    Kentaro will be in one of the below three
     remote observation room (night in Hawaii) 1-808-934-5059
     library (afternoon in Hawaii) 1-808-934-5072
     room for stay 1-808-959-6097
     kmotohara@ioa.s.u-tokyo.ac.jp

    For Suprime-Cam observations, Naoki Yasuda is in charge.
     office: 81-422-34-3579
     naoki.yasuda@nao.ac.jp

    Also we would like to have a video/phone meeting on the 22nd
    (in Chile) including LBNL and Subaru people, if you are
    convenient. Please tell us your schedule.

    Kentaro Motohara and M.Doi will be in Chile (Atacama, Las
    Campanas, and Santiago) from Nov.24 to Dec.13.

    Cheers,

    -Mamoru
