Spitzer Documentation & Tools
MIPS Instrument Handbook


Appendix A.      Version Log

Version 3.0, March 2011:


Some very minor updates to text and headings for better clarity and readability. Added more references to Level 1 (BCD) and Level 2 (post-BCD) data for clearer connection to data products delivered by the Spitzer Heritage Archive.


Made minor corrections to listed MIPS zero points and their errors.


Added mention of S18.13 pipeline label to pipeline history log. It is identical to S18.12.


Removed references to obsolete software LEOPARD in favor or the Spitzer Heritage Archive.


Version 2.0, September 2010:


        The data products list in Chapter 6 was updated to include a description of all files being delivered by the Spitzer Heritage Archive. Descriptions of files not delivered were removed. Minor corrections made on labeling of RAW vs. BCD products.


A history of pipeline changes of conversion factors (DN to MJy) was added to section 4.3.2. Fixed incorrect conversion factor reference that remained in text (not in table).


Update/corrections to bit mask tables in section 6.5. Additional text describing fatal bits rejected by default MOPEX mosaic pipeline added.


       Some additional KEYWORD descriptions added to Header Keywords, section 6.6.


       Improvement in legibility of several figures (Figures 2.14, 2.15, 3.17, 3.18).


Added version log appendix and lists of Tables and Figures.


Version 1.0, February 2010:

The first version of the MIPS instrument Handbook, which includes information from the MIPS Data Handbook, the Cryogenic Spitzer Observerís Manual, and Spitzer Science Center webpages.
