How did we score the significance (Shinkai, Ando) ?
- The significance is only in case of KAGRA upgrades but not for the general GW detector
It is suggested to use Feasibility only instead multiplying by significance (Ando)
- We will consider for that
How do we weight between science and technology ? For example what if we have one strong science case which needs difficult technology or oppositely we can also make a judgement based on technological feasibilities
- We should take both into account, is we achieve some upgrades in the next 5 years we have to put some weights on the feasibility. For the moment our recommending two options (FDsq and HF) also show strong science cases but more qualitative evaluation should be done
