Observing at WMKO
Instruments Available for Semester 2014B

For detailed information about the instruments, please check the Instruments Home Page
For a Resolving Power vs. Wavelength comparison of Keck instruments, please check this Instrument Comparison graph.

Keck 1 Instruments are:

        HIRESb (blue x-disperser)
        HIRESr (red x-disperser)
        LRIS-ADC (red and blue, with ADC)
        LRISp-ADC (polarimeter, with ADC)
        OSIRIS-LGS (see LGS below)

Keck 2 Instruments are:

        ESIi (ESI with the Integral Field Unit)
        NIRSPEC (without AO)
        NIRSPAO-NGS (NIRSPEC with Natural Guide Star AO)
        NIRSPAO-LGS (NIRSPEC with Laser Guide Star AO; see LGS below)
        NIRC2-LGS (see LGS below)

Subaru Time Exchange Instruments are:

        Suprime-Cam (limited), FOCAS, HDS, MOIRCS (limited), IRCS (with NGS/LGSAO with 188 elements), FMOS, COMICS, and Hyper Suprime-Cam (limited, shared risk). See below for limitations.

Telescope Limits

Please note that Keck I and Keck II have different eastern and western telescope limits. This affects the times objects will be available for observing. Objects can be acquired earlier on Keck II and followed later on Keck I.

Special Notes for Semester 2014B:

Visitor Instruments: WMKO will not support any visitor instruments during semester 2014B.

NIRSPEC: NIRSPEC will undergo a "warm and pump" service mission in August 2014 and thus will be unavailable for that month.

DEIMOS: DEIMOS will undergo a service mission beginning in January 2015 and will be unavailable that month. It is likely the service mission will extend into the first weeks of February 2015 (semester 2015A)

Suprime-Cam (limited), FOCAS, HDS, MOIRCS (limited), IRCS (with NGS/LGSAO with 188 elements), FMOS, COMICS, and Hyper Suprime-Cam (limited) at Subaru: Through an exchange with the Subaru Observatory, several nights may be available to observers who would like to use any of these instruments. Please check the Subaru web site for detailed descriptions of these instruments and the Subaru Call for Proposals for instrument restrictions, particularly for S-Cam and MOIRCS. Subaru time may be traded for time on both Keck telescopes, the exact number of nights depending both on the Keck and the Subaru demand. Neither Keck nor Subaru will support Target of Opportunity (ToO) observations during the exchanged nights. All observations will be executed in the "classical" observing mode. During semester 2014B Hyper Suprime-Cam is being offered to the Keck community for a small number of nights (exact number to be determined in April) in a shared-risk mode.

LGS-AO: For semester 2014B there will be no restrictions on the number of LGS nights nor their distribution between telescopes. NIRC2, OSIRIS, and NIRSPAO with laser guide star adaptive optics will be available. A more detailed set of guidelines for these nights and information on the capabilities of the systems may be found on the LGS-AO page. Backup programs for LGS proposals are essential. Backup programs for LGS may be either NGS programs or non-AO (seeing limited) NIRSPEC on Keck II. Non-AO NIRSPEC is not available when NIRSPEC is in the AO configuration.

AO Upgrades: The new near-IR tip/tilt system on Keck I, TRICK, is being commissioned during semester 2014A and will be available on a shared-risk basis during 2014B. Proposals should not rely on its availability, however. On Keck II we plan to switch to the new center launch laser system (CLS) sometime during the 2014A semester, providing the Keck II AO system with improved high order wavefront correction.

KOA (Keck Observatory Archive): Data from all instruments will be archived in the Keck Observatory Archive (KOA). The default proprietary period for all data is 18 months. If observers desire a different proprietary period they may request this through the Keck coversheet. Please see the KOA homepage for information on the archive. Please also see the KOA proprietary period policy.
