comment Improving convergence in a numerical integration (Version 5.2)
I suspect it will help if you break that double integral into nested integrals, and break the inner integral into to parts split at the value of the outer integral -- ( thus getting rid of the Abs ).

comment Symbolize Subscript doesn't work
Just checked: SetAttributes[Subscript, HoldAll] indeed prevents the value substitution, but the result still is not recognized as a symbol that can for example be used in the function definition pattern.

comment How to obtain the GIF by Mathematica?
have you tried something, or did you just find a picture and want someone to write code for you to recreate it? There is no dark side in the moon, really. Matter of fact, it's all dark.

comment How to calculate the analytical result of this singular integral?
note he wants 0<b<1, which is where the singularity pops up (at x=1/Sqrt[1-b^2]) . Do we have some reason to think this is convergent when Integrate and NIntegrate say it is not?

minor point but you need a space between a x

Good call! I assumed the problem was with NDSolve as well..

comment symbolic integration error
oddly it gets it correct if we split up the integral as Integrate[ .. ,{x,-1,1/2}]+Integrate[..,{x,1/2,1}] (depending on where you make the cut you get either the right or the wrong result.. )

comment How to extract the probability density function from SmoothHistogram?
one small issue to be aware of , the plot range of SmoothHistogram seems to cut off the very ends of the tails.

comment Importing FITS file from HEALPix
the raw data is a 3072x4096 byte array. Once you have that you can sort out how to partition it up. There is also a ton of header information (stored in hh in the above code) - i didn't study it to see if it describes the data structure.
