Remove frame transfer smear
This program removes the frame transfer smear from a CCD
camera. Transfer smear is the build up of residual enegy as the data is read
from the detector, line by line. The current algorithm is written to remove smear for a
CCD that reads data at the top of the detector. No visual examples have
been included because, the difference between the input and output is only a
few DN values.

Correction Values
The exposure duration value to be used in the smear calculation.
Exposure duration is the value of time between the opening and closing
of a instrument aperture.
If NO value is entered by the user, the value will be filled with the exposure duration keyword from the Instrument group
The exposure duration value must be in the same units as the transfer time.
If NO value is entered by the user, the value will be filled with the exposure duration keyword from the Instrument group
The exposure duration value must be in the same units as the transfer time.

Time required to transfer data from from active imaging area.
If NO value is entered by the user, the value will be filled with the transfer time keyword from the Instrument group.
The transfer time value must be in the same units as the exposure duration
