ESO ETC SED (Spectral Energy Distribution) ASCII data files with two data columns, wavelength and flux in the indicated unit. The files have headers with comments and units. The comment character is "#". The line with units starts with "#!".

The Pickles directory has three subdirs; "all" contains are all the Pickles templates we have in the DB, "etc" is a copy of the subset normally used in the ETCs. "4MOST" uses the smaller subset unse in the 4MOST ETC.
