Attendance: Shaul, Mathieu, Ragnhild, Hans Kristian
Regrets:

• Mathieu updates - removing frequencies from 90.91 (review results again for 90.92)
• Ragnhild updates - Commander 2
• Kris update?
• ApJ Paper template exists. The overleaf link is attached.
• Cosmoglobe talk

=== Notes (Shaul) ===

• Brief discussion of Cosmoglobe.
• Brief introduction of ApJ template. MR: in which section do we include 'results after removing frequency bands'? Perhaps a new section?
• Ragnhild has started working with Commander2 - see slides (above). She is 'calibrating' her runs - fixing model parameters at input values. Recovery of CMB maps in the Galactic plane has residuals. HK thinks this is ringing on the Galactic plane; still needs to be debugged, but may not be an issue if only in the Galactic plane.
  • Slides 7,8 - noise estimate isn't quite right. MR suggests perhaps a factor of root(2)? Need to figure out.
• MR shows results with discarding frequency bands for 90.91. A discussion ensues about how to account for the increase in sigma due to lower sensitivity vs lower efficacy of foreground separation. SH suggests degrading the noise level of the nominal configuration to match with the noise level of the instrument with smaller number of bands. MR says this is an 'increase in the scope of the paper'. Need to discuss some more. (Clem suggest increasing the number of simulations.)
