Large Programs at CFHT

We are currently executing the 2017 - 2019 Large Programs.

The very first large program at CFHT was the CFHTLS which was started mid-2003 and finished in 2009. More than 2300 hours over 5 years (an equivalent of 450 nights per year) have been devoted to the survey using MegaCam.

Since 2008, CFHT went to smaller and more numerous LPs. The observing time can use several instruments and can be spread evenly over all semesters or concentrated on fewer (specified) semesters. Programs with more spread out time allocations are generally more robust to weather losses. Also, multi-agency proposals were greatly encouraged. The 2008-2012 round and the 2013-2016 round were based on this model.

With the 2017-2019 proposals, CFHT is executing larger programs over a period of three years. Three programs are being executed, the Canada-France Imaging Survey (CFIS), VESTIGE: A Virgo Environmental Survey Tracing Ioniused Gas Emission and The CFHT Infrared Parallax Program: Mapping the Brown Dwarf-Exoplanet Connection. This will ensure that CFHT remains competitive in the near future and will also enhance the legacy value of our archival data.

The call for proposals for 2018B - 2022A period received 5 proposals that requested a total of 670 Nights. A total of 354.7 nights were allocated to two proposals. SIGNALS was allocated 54.7 nights on SITELLE and the SPIRou Legacy Survey was awarded 300 nights on SPIRou.
