Time Allocation Committee The NSF OIR Lab Time Allocation Committee (TAC) meets semi-annually to advise the NSF OIR Lab Director on the allocation of telescope time. The TAC comprises seven broad discipline-based panels plus special panels to handle survey or other proposals. TAC members are appointed by the chair of the NSF OIR Lab TAC process.
