-On this page we log the amount of SPIRou time allocated by the TACs (SLS/SPICE 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 (5 hr ​from 2022b), 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/SPICE/​PLANETS ​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 hr for MegaCam (5.5 hr up to 2022a), 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, mirror support) 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 largely suffered from these issues**with cumulated scheduled time not balancing the allocated time by 4.6 nights, whereas the other main CFHT instrument ​MegaCam ​was scheduled 40.3 more nights than allocated, i.e. about **45 more nights than SPIRou ​on the same time span**.  (We recall that in average, CFHT is meant to schedule time for each instrument in proportion to the allocated time).  ​+Following the various technical operations (aluminizing,​ engineering),​ issues (crane, hydraulics, mirror support) 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 ​until late 2023when crane problem prevented ​MegaCam ​and WIRCAM to be mounted ​on the telescope for several months.  (We recall that in average, CFHT is meant to schedule time for each instrument in proportion to the allocated time).  ​
