A Real piece of Sky: Chromatic Atmospheric Effects and the NEID Spectrograph

Lennon Nichol

One of the decadal keystones for EPRV spectrographs is reaching the minimum 8-10 cm/s precision goal, enabling the detection of Earth-like exoplanets. We seek to commission an exposure meter for the NEID spectrograph to ensure the proper application of wavelength-dependent barycentric corrections. We have investigated the data product pipeline SSBJD and SSBRV through calculation of the flux weighted midpoint time and geometric midpoint time. We verify many of these key data products, address several concerns due to hardware limitations, and discuss preliminary results as to whether the exposure meter is functioning as intended.
