Spectrograph: 2.3m at Mount Stromblo

Double Beam Spectrograph.


Use of a raster 1160*150 pixels. The A/D converter had a gain de 1e/ADU, good linearity up to 65300 ADU.
Grating: 600 lines/mm, dispersion 1.1A/pixel (15 microns).
slit: 2" on the sky (approximativement). The arc lamps lines had FWHM less than 3 pixels with good focus. Use of the mode "vertical slit on sky".
