These are FFIs from 03-oct-92. The data were treated by Carl Foley for his thesis, in which scattering and vignetting were analyzed, and estimates derived for temperatures in the northern coronal hole. See also the SHOW_PIX entry for a discussion and images.
The data are offered here in two levels of preparation: raw and composite. FFIs in two filters, with three different exposure durations, are included. Foley created composites of "long+short" exposures (like SFDs) to remove the effects of pixel saturation. The raw images are presented in this gzipped IDL save-file, and have not been prepared in any way. The composites (short+medium+long, created with SXT_COMPOSITE), are in this gzipped save-file. Uncertainties are included with the composite images.
The raw images are as follows, listing the ThinAl first:
