matlab.io.fits.getHDUtype

Get type of current HDU in FITS file

Syntax

htype = getHDUtype(fptr)

htype = getHDUtype(fptr) returns the type of the current HDU in the FITS file. The possible values for htype are:

'IMAGE_HDU'

'ASCII_TBL'

'BINARY_TBL'

This function corresponds to the fits_get_hdu_type (ffghdt) function in the CFITSIO library C API.

import matlab.io.*
fptr = fits.openFile('tst0012.fits');
n = fits.getNumHDUs(fptr);
for j = 1:n
    fits.getHDUtype(fptr);
end
fits.closeFile(fptr);
