| Detector Type (?) : | Energy counter |
| Band Name (?) : | Y |
| Obs. Facility (?) : | Subaru |
| Instrument (?) : | MOIRCS |
| Comments (?) : | The Y broadband filter is newly installed in July 2007. However the detail of the performance is still not well determined yet. The turret position of Y-band filter was changed in July 2008, so the flatfielding pattern will change. |
