=== Notes (Shaul) === \\

    * Commander: 
      * Unni has produced maps with nside=512 for 90.91, r=0 and r=0.003, 10 simulations for each. She is now doing 90.92. 
      * Ragnhild is analyzing 90.91. It takes time to run the code because of the higher resolution. 

    * Paper: 
      * Jacques volunteers to contribute to the introduction
      * Ragnhild began describing the models. She will write also the part about the map simulations. 
      * Jacques will write about model98
      * Clem will write about making the maps
      * Request to make a clear distinction between 'Foreground Models' and 'Sky Maps'
        * Clem will write the 'Foreground Models' at least for those that match S4 and the 'Sky Maps'. 
      * NILC and Commander techniques - cite other sources heavily. No need to repeat material described elsewhere
 
    * Delensing {{ :delensedb_7_.pdf | Alex and Colin's delensing figure}}
      * Colin ran a harmonic space ILC calculation. Gave noise value post calculation to Alex who ran an iterative delensing code. 
      * Deproj0 - Standard ILC, no constraints
      * Deproj1 - ILC constrained to suppress a dust SED
      * Deproj2 - ILC constrained to suppress synchrotron SED
      * Deproj3 - ILC constrained to suppress both
      * Note: everything done in harmonic space. So no spatial information about dust or synchrotron distribution
      * Discussion ensues with MR about what level of delensing he should use.
