Title: Final Calibrations for the ``SweetSpot'' Survey

Abstract: We ask for one night of WIYN+WHIRC time to obtain two last host galaxy template images to complete the SweetSpot program to observe Type Ia supernovae in the NIR (2012B-0500). The originally approved SweetSpot observed 114 Type Ia supernovae during its six semester run. Host galaxy template images were gathered during the main survey and in additional time allotted in 2015B and 2016A semesters (2012B-0500, 2015B- 0347). We require two more host galaxy template observations to assemble all necessary reference images to allow accurate measurement of the supernova flux, and thus distance, for the supernovae observed in the last semesters of SweetSpot. We will also take this opportunity to complete a network of standard stars spanning a wide color range to improve the the calibration of WIYN's GPS-based precipitable water vapor measurement system.
