CoRoT FITS files read error
These are FITS binary tables not FITS images so the normal FITS image tools very likely  won't read them. You have a couple of options to examine and manipulate them:


Use the 'fv' tool which works on FITS images or tables (and integrates with ds9)
Use TOPCAT, a very powerful tool for examining, plotting and many other operations on all formats of tables (not just FITS ones)
Use Python and AstroPy Tables e.g.


from astropy.table import Table

table = Table.read('EN2_STAR_CHR_0102990364_20070206T133547_20070401T235934.fits') 
table
