Hi all,
Because of scattered lights of the moon, we could
get useful(clean) data of 017 only for 2-hours
(seeing 0.6arcsec or better), though we integrated
more with worse seeing and large scattered lights.
Since the scattered lights are much worse than
they usually are, we asked the day clue to look
into the problem more carefully tomorrow.
According to Kentaro Motohara, the signal
to noise ratio of 017 is S/N~3 for 2-hours exposures.
Compared with the other objects in the fields, he
has an impression that 017 may be less luminous than
expected.
Tomorrow we would like to change the target
from 017 to 071, which, we think, is a more reliable
target in terms of spectrum quality and redshift
information.
And then we will decide which CISCO will go deep
for the last two nights.
