Problem in reading FITS file from fitsread.
in [Matlab]
|
From: MAYUR on 3 Jul 2010 10:19 I have many fits file with the extension .lc (denoting light curves). Running one of them with fitsinfo its giving: FileSize: 60480 Contents: {'Primary' 'Binary Table' 'Binary Table' 'Binary Table'} PrimaryData: [1x1 struct] BinaryTable: [1x3 struct] And by running fitsread: x = fitsread('sw00100319000b_1chan_1s.lc','bintable') ans = [43x1 double] [43x1 double] [43x1 double] [43x1 double] [43x1 double] which is accurate, but the size(x) is only giving 1 5. Which means, its not reading the whole data, just the table header. Can somebody tell me how to read data from the file. If you need the file, i have uploaded it on 2shared.com: http://www.2shared.com/file/As6YYZU8/sw00100319000b_1chan_64ms.html just click on Save file to your PC in the down-right corner. Please help.

Which means, its not reading the whole data, just the table header. Can somebody tell me how to read data from the file. nedless to say: the size IS correct... X is a CELL of size 1 x 5, ie, five CELL members, each of which with a size of 43 x 1... to see what happens, do this x{1} cat(2,x{:}) us
