CDN-346: The Mean-Coherence Tradeoff

Puntos clave

This research aims to explore the relationship between median halo concentration and coherence within the CDN lensing framework.
Used the CDN-344/345 prior model with sigma_log10(c)=0.15 dex.
Mapped tradeoffs between median halo concentration and common-mode coherence.
Assessed fixed c0=10 conditions and analyzed the impacts of adjustments in concentration.
An upward shift in median concentration can significantly reduce required coherence.
The findings indicate that a sub-one-sigma increase in concentration substitutes for high-coherence demands.
The locked result is ONE_SIGMA_MEAN_SHIFT_CLOSES_INDEPENDENT_TAIL.

Resumen

CDN-346 maps the tradeoff between median halo concentration and common-mode coherence in the GCFT/CDN lensing closure framework. Using the locked CDN-344/345 prior model with sigmaₗog10 (c) =0. 15 dex, it shows that the high-coherence demand found at fixed c0=10 is not unique: a sub-one-sigma upward shift in median concentration can substitute for much of the required coherence. The locked result is ONESIGMAMEANSHIFTCLOSESINDEPENDENTTAIL.
