 +  * Julien + Sebastian: Clem produced maps but foreground information drops at \ell=1500. For S4 power does not drop for some models. **Shaul will check with Clem**. 
 +    * JD: PySM is an nside=512 which gives \ell = 1500. They are working on increasing nside but it isn't ready yet. PSM maps have information going to \ell=5000. 
 +    * SH: do we need information at high \ell? JD shows spectra of dust maps between 40-220 GHz that show power to high \ell
 +    * Julien: S4 needed only minimal separation using the central frequency bands. This is not an issue for a small clean patch, but may be an issue for 50% of the sky
 +    * Kris: what about point sources? 
 +    * JD: for CORE we have done cleaning at nside=2048.

 +  * Charles gives outline for gap list paper (see below). SH: there is a specific form that needs to be filled. We need to highlight urgency, such as 'critical', or 'mission enhancing'. Perhaps 10-20 GHz would be 'mission enhancing'; do we know we can call it critical?

 +Hi Shaul & Co.:
 +
 +As promised, here's a draft outline of the case for broadening the frequency range of the tech gap list on CMB detectors.
 +
 +1. Intro
 +    statement of what we're writing about.  Overview or argument.  Context of space CMB mission science requirements.
 +
 +2. high frequency (now 600, we'll argue to raise to 800)
 +    results of simulations, showing the improvement in CMB extraction with the addition of frequencies between 600 and 800 GHz
 +    at least one figure.  What's the best one to use?
 +
 +3. low frequency (now 30, we'll argue to lower to 10)
 +    "practical" argument from Oslo about SNR and real estate
 +    if we have any simulation results that seem relevant, we'll use them, otherwise say that we don't yet.
 +
 +4. summary
