Updates to the WFC3/IR Photometric Stability Stellar Cluster Study
Ky Huynh, Varun Bajaj
The WFC3/IR channel has been shown to lose sensitivity over time. The sensitivity loss rate has been quantified in past works and we extend those measurements into 2026 using photo…
A Look at Eight Outbursts of Comet 7P/Pons-Winnecke
Ky Huynh, Michael S. P. Kelley, Jessica M. Sunshine +6
Cometary outbursts may be used as a means to infer the physical processes occurring on cometary nuclei. To that end, we studied eight outbursts of comet 7P/Pons-Winnecke identified…
Testing and Validation of the Updated Pixel-Based Non-Linearity Calibration File for WFC3/IR
K. Huynh, V. Bajaj, M. Marinelli +3
The WFC3\IR channel has an innate non-linear response to incident photons, which is corrected for in the calwf3 pipeline with the NLINFILE reference file. The 2009 solution is base…
Pixel-Based Non-Linearity Correction for the WFC3 IR Detector
Sachindev S. Shenoy, Ky Huynh, Varun Bajaj +1
The current non-linearity correction for the Wide Field Camera 3 Infrared (WFC3/IR) channel is based on ground-based data acquired during WFC3's Thermal Vacuum 3 (TV3) testing camp…
