comment Interact with external program
NMinimize needs a lot of candidates to do the job, there is no shortcut, except setting precision of the result. If your function has nice analytic shape, you may also consider using some fitting procedure to fit to that shape. Otherwise NMinimize has to search manually for the minimum, but you can also change the method of the search. Could you be more specific on the problem considering OpenWrite and OpenRead?

comment Disable alert message with internet connectivity off
Just allow automatic updates and restart Mathematica once. After that you can disable internet connectivity again and there will be no pop-ups appearing.

comment Importing FITS file from HEALPix
Thank you, George. This is extensive code. The image is a simulated CMB map, so it should not look like this at all. It has colours and I think the file should contain 5 (or 7) columns of 8bit numbers that can be plotted as colours. As I said, it is probably to difficult to get this, since HEALPix is probably using a modified FITS format (which is open source), and hence it is not standard any more...

@mfvonh: Thank you. Here is the FITS file, which makes the trouble.

comment Importing FITS file from HEALPix
@mfvonh: Unfortunatelly, uploading never finishes. It seems 13MB is too much. I'll try to make a smaller example file. However, I discovered that neither IDL can open the FITS file from HEALPix. It seems these guys modified the format a little bit and have even created a specific function in IDL to work with their format. The only hope know is to use a header of the FITS file and understand the structure of the rest of the file which is binary.

Sure, Yi, only that this is a FITS file format
