*******************************************
Figures for the visual grism : clocked mode
*******************************************

These figures go with the description :ref:`fluxcal_verification_955`, 
and show in the top panel the observed flux and the reference spectrum
which is usually taken by HST. 

In the bottom panel is plotted (observed - reference)/reference as a percentage. 
Notice that the bottom plot gets very noisy when the source flux is low. This is 
due to noise in the data. Also, at longer wavelengths second order contamination
raises the observed flux, setting in at a wavelength that depends on the location 
of the blue rise of the spectrum.
