Time-critical ------------- No. Objective --------- The purpose of these observations is to provide a reference photometric catalog to support the NISP-S spectral observations of a Planetary Nebula (PN). In particular, the NISP-P data will be used to determine the wavelength zeropoints for the NISP-S spectral dispersion solution.
