We report on the global properties of the Fe feature seen in the 6-7keV spectra of X-ray sources observed with the EXOSAT Gas Scintillation Proportional Counter (GSPC). Of a total of 431 spectra extracted from the EXOSAT archive, 205 required the addition of a Gaussian emission line to the continuum spectrum in order to obtain satisfactory fits. The majority of these sources are X-ray binaries. The best fit line properties are given for each of these spectra as well as being summarized by source class. For the 226 spectra which did not require the addition of an emission feature, upper limit equivalent widths for narrow and broad lines are presented.
