(1) The flux data is taken from http://www.stsci.edu/hst/observatory/cdbs/calspec.html
(2) Because the target is larger than the spectrograph slit,these spectra are from part of the instead of the integrated planet spectrum.
(3) The signal in November 20 for Venus is in good agreement with the spectra taken by Pollack (1978). Compared to the Nov. 20th spectrum, the Nov. 26th signal has the same shape, but the region from 1 to 1.8 $\mu $m appears depressed, though the origin is not known.
