The number of nights in ( ) for the HSC Queue programs indicates 1/0.7 times requested observation nights to consider the weather factor.
The instruments and nights written in italics are those of Gemini or Keck Telescopes, with which we have time-exchange programs.
- This proposal has been accepted in the category of Intensive Program and a total of 32 nights will be allocated from S24A to S26A.
NOTE
Additional five nights were allocated.
