Hi Saul,
We have observed 35-min exposures of SXDS1-5
with Suprime-Cam. The sky was often hazy/cloudy
1-2 hours after we started. The seeing is mostly
good, < 0.6arcsec. We took SXDS2 and SXDS5 under
reasonably good transparency. Some of the images
of SXDS1 were taken in bad(hazy/cloudy) conditions,
and we added 10min extra (total 45min) exposures
of SXDS1 under reasonably good conditions. We
won't have no more exposures in i'-band tonight.
The exposures should be mostly O.K. to get light
curves (at near maximum) of SNe which are not very
faint. Naoki is checking the depth.
>Our first (easy, bright) target of the night was 019, which had a
>photo-z of 0.7, but we got a host galaxy redshift of z = 0.505 [from
>lots and lots of lines: OII (5606 and 5610), OIII (7533), Halpha (7315),
>OIII (7461)].
O.K. There were two candidates of the host of 019, and
after I told you the first results of photo-z, more careful
identifications were made, and the photo-z of the nearest
object of 019 became 0.50 and 0.49, well matched to the answer.
I didn't update the information, sorry.
In any case, we down-graded the priority for spectroscopy
of 019, and we confirmed it now.
