Box vs Optimal

Load data



In [3]:

    
spfile = '/Users/xavier/REDUX/Keck/LRIS/2017jan30/blue_A/Science/spec1d_UCG3672A_LRISb_2017Jan30T064821.fits'



In [11]:

    
box_flux = arload.load_1dspec(spfile, objname='O220-S1466-D02-I0010', flux=True, extract='box')
opt_flux = arload.load_1dspec(spfile, objname='O220-S1466-D02-I0010', extract='opt',flux=True)

Compare



In [14]:

    
plt.clf()
ax = plt.gca()
ax.plot(box_flux.wavelength, box_flux.flux)
ax.plot(opt_flux.wavelength, opt_flux.flux)
plt.show()

Results are very good

Consistent to within 10%
