Memo by Minowa-san
--------------------------- === FOCAS === Lee: ADC, Short wavelength cannot do with GMOS HSC users tend to do follow-up with FOCAS, GMOS,... Iwata: Keck LRIS has better sensitivity in blue than FOCAS Operation wise it is difficult to maintain FOCAS (or any Cs instruments) in the PFS era. Aoki: HSC requires spec follow up anyway. Instrument exchange from PFS to HSC or vice versa takes time or and difficult FOCAS is more convenient than PFS Hattori: How much longer will LRIS/GMOS survive? Iwata: There is no plan to decommission GMOS, LRIS as well. KCWI is supposed to be available in 2017. But Keck will continue to use LRIS after KCWI. Minowa: ULTIMATE does not necessary to decommission any Cs instrument. ULTIMATE ASM and WFS can feed any Cs instrument. === MOIRCS === Aoki: MOIRCS IFU. There is a risk of failure after IFU implementation. Iwata: IFU will not destroy the existing focal plane unit, but require careful consideration to decide if IFU is installed or not. MOIRCS IFU is not so important for ULTIMATE. ===COMICS === Minowa: COMICS can be substituted by MIMIZUKU at TAO === HDS === Pyo: HDS is basic, but most important instrument. Worth remaining ,,,, === IRCS === Kim: Most of IRCS service proposal requests thermal infrared observation. Aoki: JWST can be competitor for IRCS long wavelength === General === We should divide the instrument plan for PFS era and ULTIMATE era. [EOF] ---------------------------
