<strong>GMOS</strong> MOS Spectra! Alignment stars!
<strong>GMOS</strong> MOS reduction! Basic reduction steps! � Prepare the images by adding the MDF file with gprepare! � Bias subtraction for all images, including the CuAr arcs! � Cuar arcs observed during the day - then an overscan subtraction is enough.! � Bias subtraction is performed with gsreduce ! � gsreduce @obj.lst fl_flat- fl_gmosaic- fl_fixpix- \ fl_gsappw- fl_cut- fl_over+ fl_bias+ bias=biasima.fits \ rawpath=dir$ mdfdir=dir$!
