It is reminded that CAT approved ToO proposals can use only CAT time on the NOT.
ToO proposal 74-NOT7/26A (PI: Iván Agudo) is permitted up to 27 h with overrides of 4 h per night with ALFOSC during CAT SERVICE time, and has prioriy over all other ToO proposals.
ToO proposal 125-MULTIPLE-4/26A (PI: Sara Rastello) is permitted up to 5 h with ALFOSC with overrides of 0.55 h per night. It can override CAT service time and CAT proposals: 19-NOT2/26A, 104-NOT14/26A, 124-NOT16/26A, and 53-NOT5/26A.
ToO proposal 99-MULTIPLE-4/26A (PI: Frédérick Poidevin) is permitted up to 6 h with ALFOSC with overrides of 0.083 h and 0.92 h per night. It can CAT service time and CAT proposals: 124-NOT16/26A, and 53-NOT5/26A.
ToO proposal 91-MULTIPLE-9/26A (PI: Alessandro Ederoclite) is permitted up to 2.4 h with ALFOSC and FIES with overrides of 0.2 h per night and instrument. It can CAT service time and CAT proposals: 124-NOT16/26A, and 53-NOT5/26A.
