... Consequently, it is inappropriate to expand and in ordinary spherical harmonics. The proper expansion expresses both and simultaneously in terms of a particular order of generalized spherical harmonics. ... Generalized spherical harmonics start at , and for each , . ... Generalized spherical harmonics obey a sum rule analogous to a familiar one for ordinary spherical harmonics, but it includes an explicit phase factor which depends on the orientation of the two lines of sight. ...

... Stars . ... To understand what has happened we need to consider an often-overlooked class of object, the white dwarfs. New research shows that some old stars known as white dwarfs might be held up by their rapid spins, and when they slow down, they explode as Type Ia supernovae. ... However, give a white dwarf a very close companion star and you could have an explosion visible across the Universe. ... This, however, is not the only catastrophe that can befall such a white dwarf star. ...

Hence to change the values the TCC is actually using, you must not only edit the file(s), but also load the new data by issuing the appropriate SET INSTRUMENT command. ...
... Due to the presence of instrumental noise, however, it is clear that the inverse, R \Gamma1 , of the response matrix at each Fourier mode does not exist and that the linear inversion problem in each case is degenerate. ... If the instrumental noise on each frequency channel is Gaussiandistributed, then at each Fourier mode the probability distribution of the n f component noise vector ffl is described by an n f dimensional multivariate Gaussian. ...

Log of Changes Made to CFITSIO Version 3.31 - 18 July 2012 - enhanced the CFITSIO column filtering syntax to allow the comma, in addition to the semi-colon, to be used to separate clauses, for example: [col X,Y;Z = max(X,Y)]. This was done because users are not allowed to enter the semi-colon character in the on-line Hera data processing system due to computer security concerns. - enhanced the CFITSIO extended filename syntax to allow specifying image compression parameters (e.g. '[compress Rice]') when

... The most important tool you have to see the universe is not the large light buckets that are proliferating, but rather your eyes. ... Light enters the eye through the cornea, passes across the aqueous humor (the liquid behind the cornea), passes through the pupil and through the lens. ... After passing the lens, the light then crosses the "vitreous Humor" a jelly-like substance that fills the inner eye, and reaches the retina, the light sensitive tissue at the back of the eye. ...
