The instruments and nights written in italics are those of Gemini or Keck Telescopes, with which we have time-exchange programs.

NOTE
In order to compensate surplus telescope times, which resulted from the interminacy of telescope schedule after the re-coating of the primary mirror, three backup proposals (see 1 below) were newly accepted and supplemental nights were added to two already accepted proposals (see 2 below).
