Wide Field Camera 3 Instrument Handbookfor Cycle 22 > Chapter 1: Introduction to WFC3 > 1.1 What’s New for Cycle 22

1.1
We have made the standard updates to this Handbook, including the addition of references (throughout the Handbook) to the WFC3 Instrument Science Reports that were published in the past year and a summary of the WFC3 calibration plan for the upcoming cycle (Appendix E:Reduction and Calibration of WFC3 Data). Additional updates include:
Changes in the WFC3/UVIS dark current (Table 5.1, Section 5.4.8) and the number of hot pixels (Section 5.4.9) which result from measuring dark exposures made with post-flash to reduce CTE losses (Section 6.9.2), since fewer electrons appear to trail out of hot pixels into adjacent pixels
Illustration of a diagram that can be generated in APT (Figure 8.9) to visualize the start and end of a spatial scan, an observing technique discussed in Sections 6.11.3, 7.10.4, and 8.6.
