Scientific paper

Using data taken during thermal vacuum 3 (TV3) testing, we have measured the magnitude and stability of the dark current plus thermal background signal present in WFC3's IR channel. We find that the IR channel with the flight detector (IR4) meets the Contract End Item (CEI) specifications for total background signal and background stability. Additionally, the background levels presented here should be interpreted as upper limits, due to persistence effects from a previous test.
