LhiresIII observations

20120813_060_AZcas_Lhires_halpha MJD 56152.5596

Centered on h alpha (6502A-6608A) taken on August 13.06, with a LhiresIII spectrograph, 2400gr/mm, R=15000, disp 0,16A/pix, attached to a 0,212m f10 cassegrain reflector. Calibration has been done on a spectra of an internal neon lamp. Standart pre processing applied, instrumental response corrected with a spectra of Vega. not normalized.
Observers are Paolo Berardi and me during 2012 OHP spectroscopy workshop. No heliocentric and no telluric corrections. date MJD 2400000+
