 On this page we log the amount of SPIRou time allocated by the TACs (SLS and A&​B-rated PI programmes) and scheduled on the telescope since the beginning of semester 2019a, comparing both to those of the other CFHT instruments (all numbers taken from [[http://​www.cfht.hawaii.edu/​en/​science/​QSO/​|CFHT QSO pages]]). ​ We quantify the **overall time pressure** on each instrument by computing the **difference between the allocated and scheduled amounts** since 2019a. ​ (We recall that 1 night of telescope time amounts to 7 hr for SPIRou, 5.5 hr for MegaCam, 7.5 hr for ESPaDOnS, 5 hr for WIRCAM and 6.5 hr for SITELLE).  ​ On this page we log the amount of SPIRou time allocated by the TACs (SLS and A&​B-rated PI programmes) and scheduled on the telescope since the beginning of semester 2019a, comparing both to those of the other CFHT instruments (all numbers taken from [[http://​www.cfht.hawaii.edu/​en/​science/​QSO/​|CFHT QSO pages]]). ​ We quantify the **overall time pressure** on each instrument by computing the **difference between the allocated and scheduled amounts** since 2019a. ​ (We recall that 1 night of telescope time amounts to 7 hr for SPIRou, 5.5 hr for MegaCam, 7.5 hr for ESPaDOnS, 5 hr for WIRCAM and 6.5 hr for SITELLE).  ​
  
-Following the various technical operations (aluminizing,​ engineering),​ issues (crane, hydraulics) and shutdowns (TMT protests, COVID-19) that CFHT underwent since 2019a (generating an overall loss of 126 nights),​ only MegaCam was scheduled enough time on the telescope to carry out the allocated programmes. ​ **SPIRou suffered a lot from these issues**, with a cumulated allocated minus scheduled time deficit **reaching ​5.6 nights since 2019a**, i.e., 20.9 nights larger than that of the other main CFHT instrument MegaCam.  ​+Following the various technical operations (aluminizing,​ engineering),​ issues (crane, hydraulics) and shutdowns (TMT protests, COVID-19) that CFHT underwent since 2019a (generating an overall loss of 126 nights),​ only MegaCam was scheduled enough time on the telescope to carry out the allocated programmes. ​ **SPIRou suffered a lot from these issues**, with a cumulated allocated minus scheduled time deficit **reaching ​4.6 nights since 2019a**, i.e., 19.9 nights larger than that of the other main CFHT instrument MegaCam.  ​
