Appendix I. Version Log Version 2.0.2, March 2012: S 18.24 added to Appendix A Version 2.0.1, June 2011: Reference to Krick et al. added to Section 4.11.5 Version 2.0, April 2011: Discussion about artifact mitigation was added to Chapter 5 (5.3). Version Log 196 IRAC Instrument Handbook A new processing version S18.18 BCD FITS header replaced the old header file in Appendix D. Discussion of a few new header keywords, including timing keywords and bad data value keywords, was added in Section 6.2. The filenames in Table 6.1 were updated. Added information about warm mission persistent images and edited the information on cryogenic mission persistent images in Section 7.2.8. Added information about the effect of very deep surface brightness level observations in Section 4.11. Added an Index at the end of the document. Version 1.0, February 2010: The first version of the IRAC Instrument Handbook, which includes information from the old IRAC Data Handbook, the old IRAC Pipeline Description Document, the cryogenic Spitzer Observer’s Manual (SOM), and Spitzer Science Center web pages.
