Instruments are divided into facility instruments and PI instruments.
Facility instruments are available for all users
PI instruments require approval of the instrument PI
prior to proposal submission
PI instruments are indicated in the list below
Magellan I (Baade)
IMACS Optical imager and multi-slit spectrograph

FIRE Infrared echelle
FourStar Wide-field Near-IR Camera
Magellan II (Clay)
LDSS-3 Optical imager and spectrograph
MagAO Magellan Adaptive Optics System
MagE Optical echellette spectrograph
MegaCam Wide-field optical imager
MIKE/M2FS Optical fiber-fed echelle spectrograph
MMIRS Infrared imager & spectrograph

Starting in the 2008B semester, we will experiment with
interventions for targets of opportunity (TOO). The
guidelines for Magellan
interventions describe the science goals and the responsibilities
for the PI and other Magellan observers.

SWIRC Infrared imager
Hectospec, Hectochelle, and MMT Cam are run in queue mode
The TAC welcomes target of opportunity proposals for the Hectospec and Hectochelle queues.
The single-object modes available with both instruments allow acquisition of TOO targets. Contact
Nelson Caldwell for details on this operation of Hectospec and Hectochelle.
The TAC also welcomes parallel proposals for the Hectospec and Hectochelle queues. Parallel
programs acquire observations with the unused fibers of the main program. Parallel observations
are completely transparent to the PIs of standard programs. The PI sets up fields in the normal
way. Once the PI submits the fields, the PI of the parallel program assigns targets to unused
fibers. Contact Nelson Caldwell for additional details on this operation of Hectospec and
Blue and Red channel Optical spectrgraphs
PISCES: IR echelle spectrgraph PI Instrument
ARIES with AO system: PI Instrument
CLIO with AO system: PI Instrument
MIRAC/BLINC with AO system: PI Instrument
MMT-POL: 1-5 micron imaging polarimeter PI Instrument
The 1.5-m is a single-object, spectroscopic telescope. Most observations are made in a queue, but scheduled time is also available.
FAST: low resolution, high throughput optical spectrograph (CCD detector)
TRES: high throughput, optical echelle spectrograph (CCD detector)
The 1.2-m is an imaging telescope with a wide-field optical camera and a moderate
field infrared camera. Most observations are made in a queue, but scheduled time is
KeplerCam: Optical camera with a 23′ by 23′ field-of-view
Pairitel is closed.
Pairitel IR Camera: JHKs imaging over a 8′ by 8′ field-of-view
Although scheduled observers may invite guests to watch operations
at the MMT, the MMTO has a strict visitor
policy that requires approval from Mr Dennis Smith, Mountain
Operations Manager. The TAC strongly supports this policy and recommends
that observers read the policy before traveling to the MMTO.
