The SNLS survey consists of:
- A large imaging survey at CFHT
Between 2003 and 2008, the
CFHT Legacy Survey
detected and monitored about 1000 supernovae with
Canada-France-Hawaii telescope .
- A large spectroscopic survey
About 500 high-redshift Type Ia SNe were observed on
8m class telescopes (Gemini, VLT, Keck).
The primary goal was to obtain Supernova identification and redshift.
Detailed spectroscopy of a subsample
of distant SNe was also done to validate the use of
Type Ia SNe as cosmological candles.
