Center-to-Limb Variation of Solar Line Profiles

Spectra acquired on October 22-23, 1997 with the Gregory Coude' Telescope and its Czerny-Turner echelle spectrograph at the Observatorio del Teide (Tenerife, Spain).

The data acquisition/reduction is described in this paper (Allende Prieto, Asplund, Fabiani Bendicho, 2004, A&A, in press).

The ASCII datafiles contain 12 vectors, each with 993 elements. The 12 vectors correspond to 6 pairs of (wavelength,flux) vectors at positions 1 through 6 (see description in the paper). Only four numbers per line are given. Here is an IDL script to read the files.

Individual files may be downloaded from the last column of the table below. Alternatively, you can download the whole dataset here.
