-  * +  * Working to make a visual we have needed.  Noise level vs frequency and signal levels.  Trying to make something that makes sense. 
 +  * This made by Josquin. 
 +  * left vertical axis is noise levels. right vertical axis is signals (CMB, dust, synchrotron) 
 +  * AK: Not a fan of uK_CMB above ~300 GHz. The upper range makes synchtron, dust, etc look odd. 
 +    * AK: Like everything in Janskies or W/m^s/sr/Hz. Something more widely used in astronomy. 
 +  * SH: Understood. This figure works for CMB community, but maybe a second product to use in a more general context. 
 +  * HH: Al's point is good.  Reach broader groups.  This plot says 'PICO is a CMB mission' contrary to the workshop message of PICO as a mm/sub-mm instrument. 
 +  * AT: Yes, more general units good. 
 +  * SH: Al can send unit suggestion to Josquin.  AK: Yes, will do. 
 +  * SH: Also planning to color code bands by pixel type. 
 +  * AT: Error in band location? SH: yes, iterating with Josquin.
