Compute pixel photometric sensitivity (volts per lux-sec)
[voltsPerLuxSec,luxsec,meanVolts] = pixelVperLuxSec([ISA])
The photometric sensitivity is computed for each of the color sensors
using a D65 input. The value can change
This routine is used to convert the pixelSNR graph from SNR vs. Volts to
SNR vx. Lux-Sec.
N.B. The value of photometrics sensitivity (V/lux-sec) depends on the
spectral power distribution of the input. If we use an equal energy
input, rather than a D65, the value changes.

Example:
[vpLS,ls,meanV] = pixelVperLuxSec;
[vpLS,ls,meanV] = pixelVperLuxSec(ISA);
