Initial commit of science programs in use.
initial commit for combine_dithered_images and interactive_extraction
add support for using predefined background and changed default deg to 5 in fitting routine
changed location and name of background region file
changed name of extracted 1D spectrum to end in x1d.fits
added comments and changed the file name of the x1d file so that the central wavelength is only listed once
added support to redefine background regions after you have started fitting the background region
Corrected bug in creating filename in extract_spectrum, added command line options --backcorr and --ncol to turn on/off background subtraction and modify the number of columns summed to make the cross-dispersion profile
Added option to set dither offset. Changes sum to mean in dither. Fixed comments
removed a stray pdf.set_trace() in collapse_spectrum
removed hard coded shift option and added option to look at the header to get the shift value
changed default ncol to 50 pixels
removed hard coded shift option and added option to look at the header to get the shift value. Also corrected error in calculation of the mean
Merge branch 'master' of github.com:abostroem/science_programs
Modified to write to the first extension and create proper primary and first extension headers
Not sure what is different
Merge branch 'master' of github.com:abostroem/science_programs
changed default background subtraction to be 'perform'
added option to control background smoothing and set the default to off. Added a dashed line at zero to the background subtracted cross dispersion profile
removed x1d from the filename of the 1D extraction files
