Chapter 1 (Introduction):     NJW
Chapter 2 (Data correction):  CAO (SB to supply gain evolution plots)
                              CAO, JC, SB Improve figures 2.10 & 2.11 by
                              wider time bins
                              CAO checks fig. 2.13
Chapter 3 (Background determination) :
                              NL write a section on how background is
                              handled in source extraction
                              NJW reduces text for background modelling
Chapter 4 (Non-imaging results):
                              PK checks the text, JC checks fig. 4.1 & 4.2
Chapter 5 (Imaging)           NL & NJW rewrites and focus on improvements
Chapter 6 (Source detection): PK section 6.1 (source position) New figures
                              NJW section 6.2 (source detection significance)
                              NJW/NL section 6.3 (source fluxes)
Chapter 7 (Source property extraction):
                              SL New Crab spectral investigations and
                              (perhaps) weak source example. New light curve
                              example if required.
Chapter between 7 and 8 (Image mosaicking):
                              JC Text and new figure(s).
