Spectra of YY Geminorum covering the H-alpha region were observed with the Coude
spectrograph on the 2.6m Shajn telescope at the Crimean Astrophysical
Observatory on 5 and 6 March 1988. The spectrograph employed a GEC CCD detector
(576x385 pixels) with a resolution of 22 microns per pixel. The exposure times
were 30 minutes. See Tuominen et al. Solar Phys. 121, 419 for further details.

The extracted spectra given in the files in this subdirectory contain 21 lines
of introduction followed by approximately 60 lines, each containing 10
wavelength values. Following this a further approximately 60 lines contain the
fluxes at each wavelength position.
