... Because the DMR instrument is differential and every pixel is multiply sampled, sky maps are produced by solving a coupled system of linear equations (the normal equations) to minimize a chi-squared. ... This is reflected in the algebraic form of the normal equations matrix, so that, if one were to diagonalize the matrix, one would find a single eigenvector whose eigenvalue was identically zero, and the associated eigenvector, viewed as a sky map, would have a constant value. ...

Here are six comparison images of the central nebula region from my 1998 AAS dissertation talk. ... Mid: Schmidt Bj (3600-5200 ) optical reflected starlight (folded scale). Bot: IRAS 100 ?m thermal emission (log scale). Right Side: Detailed HI 21cm line emission near the Pleiades, imaged by the 2 x 2 degree VLA-D survey (inset box); large-scale structure was mapped with the Green Bank 140-ft. telescope. ... These images compare the post-thesis extended VLA survey with other datasets. ...
