  1. The Spectrum algorithm for sub-national IRS allocation first excludes all Admin1 units with 0 PfPR (if any, not applicable in Nigeria). Among Admin1s with >0 PfPR, IRS gets allocated according the highest complement of ITN coverage (=100% − ITN coverage), at 90% IRS coverage (of the population living at PfPR>) for each successive Admin1 unit, until the total people protected across selected Admin1 units saturates to the national total number of people protected. The last Admin1 unit allocated IRS gets a <90% IRS coverage (for Nigeria at 2015: Kano state, with 2.5% IRS coverage), to exactly meet the national total number
