 +  * Kris: precession  
 +        * More to come on Wednesday: a preview is as follows: 
 +        * 10 hour precession period: {{:systematicswg:telecons:2018-05-14:orth_nobs_tprec10hrs_190_days.png?25|}}  
 +        * 48 hour precession period: {{:systematicswg:telecons:2018-05-14:orth_nobs_tprec48hrs_190_days.png?25|}} 
 +        * 48 hour precession leads to coherent structures, lines of high coverage.  
 +        * Kris suggests a fiducial toast simulation with 4-detector set to show full I,Q,U reconstruction in the presence, with CMB+dipole first.  Extract power spectra.     
 +              * this demonstrates PICO's basic ability to extract polarization with PICO scan, 1/f, etc. 
 +              * Andrea would be the one to run this.  Andrea reports that the easiest thing to do is to set a 4-detector single horn.  We agree that we should quickly run this, then revisit later if we want to do 2 horns, scaled noise, etc.
