`astropy.io.fits._utils:parse_header`

Signature

def parse_header ( fileobj )

Summary

Fast (and incomplete) parser for FITS headers.

Extended Summary

This parser only reads the standard 8 character keywords, and ignores the CONTINUE, COMMENT, HISTORY and HIERARCH cards. The goal is to find quickly the structural keywords needed to build the HDU objects.

The implementation is straightforward: first iterate on the 2880-bytes blocks, then iterate on the 80-bytes cards, find the value separator, and store the parsed (keyword, card image) in a dictionary.
