The lower mantle is parameterized in three layers (from the top: 670 to 1200, 1200 to 2000, and 2000 to 2891 km depth). The coarse layering is determined not by data resolution, but by computational requirements.

Average field inside a sphere - Physics Stack Exchange

WebThe average spherical aberration of the anterior cornea surface is slightly positive (between +0.27 and +0.30 μm), remaining stable throughout life. 2 The natural crystalline compensates for this positive spherical aberration, inducing a negative spherical aberration of –0.20 μm, leaving a slightly positive total aberration of +0.10 μm. WebAverage over angles. I feel quite dumb for asking this, but it's getting a bit frustrating. I have a function which depends on $\theta$ and $\phi$ in spherical coordinates: $$ f (\theta, \phi) = \sin^2 \theta \mathcal {L} + \left ( \cos^2\theta +\sin^2\phi \sin^2\theta \right) \mathcal {M} $$. where $ \mathcal {L}$ and $ \mathcal {M}$ are ... laura melancon new orleans
