The TMT Site Testing Team<br />

The TMT site selection results presented here could not have been<br />

obtained without the hard work <strong>of</strong> a large group <strong>of</strong> people :<br />

– The core Site Selection Team : Bob Blum, Edison Bustos, Sebastian Els, Paul Gillett,<br />

Brooke Gregory, Jerry Nelson, Angel Otárola, Reed Riddle, Matthias Schöck, Juan<br />

Seguel, Warren Skidmore, Eric Steinbring, Tony Travouillon, Joselino Vasquez,<br />

Konstantinos Vogiatzis, David Walker, Lianqi Wang<br />

– Approximately 90 people were directly involved in the site selection work<br />

– A special thanks to everybody who has supported, and is still supporting, the TMT site<br />

selection program, in particular the people at the Cerro Tololo Inter-American<br />

Observatory (CTIO), the National Optical Astronomy Observatory (NOAO) and the<br />

AURA New Initiatives Office (NIO), the Universidad Catolica del Norte in Ant<strong>of</strong>agasta,<br />

the Observatorio Astronomico Nacional de San Pedro Martir, Gemini Observatory,<br />

Palomar Observatory, the Submillimeter Array (SMA), the <strong>University</strong> <strong>of</strong> <strong>Hawaii</strong> Institute<br />

for Astronomy (IfA), the <strong>University</strong> <strong>of</strong> Lethbridge, the <strong>University</strong> <strong>of</strong> Moscow, the South<br />

African Astronomical Observatory (SAAO), and the entire TMT project including its<br />

partner institutions and external reviewers.<br />

The TMT Site Testing Team<br />

The TMT Sites Advisory Group was the Site Working Group in the pre-<br />

TMT days and laid a lot <strong>of</strong> the ground work :<br />

– George Djorgovski, California Institute <strong>of</strong> Technology (chair)<br />

– Alistair Walker, Cerro Tololo Inter-American Observatory (chair)<br />

– Gary Chanan, <strong>University</strong> <strong>of</strong> California, Irvine<br />

– Dave De Young, AURA New Initiatives Office<br />

– James Graham, <strong>University</strong> <strong>of</strong> California, Berkeley<br />

– Derek Salmon, Canada France <strong>Hawaii</strong> Telescope<br />

– Matthias Schöck, TMT<br />

– Eric Steinbring, Herzberg Institute <strong>of</strong> Astrophysics<br />

TMT Site Testing<br />

We started by considering all potentially interesting sites, anywhere in<br />

the world<br />

Pre-selection <strong>of</strong> five candidate sites based on satellite studies <strong>of</strong> cloud<br />

cover and precipitable water vapor and on previously existing<br />

information<br />

On-site testing with identical equipment<br />

– April 2003 to November 2009<br />

Strong emphasis on calibration <strong>of</strong> instrumentation to ensure data<br />

quality and comparability <strong>of</strong> results<br />

Final (TMT internal) site testing report and review in April 2008<br />

500m, isoplanatic angle, t0<br />

DIMM<br />

– seeing above 7m<br />

SODAR<br />

– turbulence, wind pr<strong>of</strong>iles <strong>from</strong> ground to<br />

800m<br />

Weather Station<br />

temperature, rain detection, barometric<br />

pressure, solar & net radiation, ground<br />

heat flux<br />

IRMA<br />

– water vapor<br />

Dust Sensor<br />

2.0µ, 5.0µ<br />

Sonic Anemometer<br />

– turbulence, temperature, wind speed &<br />

direction at 7m<br />

ASCA<br />

– cloud detection, light pollution<br />

30 meter Tower<br />

– sonic anemometers, temperature<br />

sensors at 11m, 20m, 30m<br />

Site Testing Computer System<br />

Impractical for manual monitoring, control <strong>of</strong> site at all times<br />

– Manpower<br />

– 24/7/365 operations<br />

If one robotic system is challenging, five could be a nightmare!<br />

– Standardization is key: all sites must operate the same way<br />

Hardware, s<strong>of</strong>tware installation<br />

Data quality<br />

Reproducibility <strong>of</strong> results<br />

Fault diagnosis<br />

Custom s<strong>of</strong>tware suite<br />

– Several instruments used commercial s<strong>of</strong>tware, integrated into system<br />

– Robotic & instrument s<strong>of</strong>tware created in house<br />

– 7 operating systems<br />

UNIX/Linux flavors, OS X, Windows<br />

– 12 scripting and programming languages<br />

IDL, Bash scripts, C, C++, awk/sed scripts, Expect scripts<br />

GNUplot, Grace<br />

HTML, Perl, PHP, Javascript<br />
