CFHTLS Wide Fields Location

The CFHTLS Wide fields location has been decided by the CFHTLS Steering Group after extensive discussions with the community of registered users. The constraints were:

  • Low dust extinction
  • Right ascension distribution over the year
  • Visibility from the VLT
  • Other surveys coverage
