Characterization and correction of charge-induced pixel shifts in DECam
Daniel Gruen, Gary M. Bernstein, Mike Jarvis +4
Interaction of charges in CCDs with the already accumulated charge distribution causes both a flux dependence of the point-spread function (an increase of observed size with flux,…
On-sky measurements of the transverse electric fields' effects in the Dark Energy Camera CCDs
Andrés A. Plazas, Gary M. Bernstein, Erin S. Sheldon
Photo-generated charge in thick, back-illuminated, fully-depleted CCDs is transported by electric fields from the silicon substrate to the collecting well at the front gate of the…
Implementation of robust image artifact removal in SWarp through clipped mean stacking
D. Gruen, S. Seitz, G. M. Bernstein
We implement an algorithm for detecting and removing artifacts from astronomical images by means of outlier rejection during stacking. Our method is capable of addressing both smal…
