A bestiary of low-level electrical artifacts in SPHEREx flight data

Candice M. Fazar, Michael Zemcov, C. Darren Dowell +3

SPHEREx, NASA's all-sky spectrophotometric survey mission, maps the sky in 102 spectral channels from 0.75 um to 5.0 um at 6.15'' resolution from low-Earth orbit using a custom rea…

Image persistence flagging for SPHEREx

Candice Fazar, C. Darren Dowell, Brendan P. Crill +3

Image persistence in HAWAII-2RG HgCdTe detectors has been observed by multiple parties. Also known as latent signal, this effect occurs when sensor images following an illumination…
