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 />

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 />
