inherited

Return detector sample.

Returns
(double) The detector sample

◆ exposureDuration()

double Isis::LineScanCameraDetectorMap::exposureDuration ( const double sample,
const double line,
const int band ) const
virtual

@breif This virtual method is for returning the exposure duration of a pixel.

For a fixed rate line scan camera this will return the line scan rate. Note that this may not be the exact same thing as the exposure duration. If there is some amount of padding between exposures, then the line scan rate is actually the exposure duration plus that padding.

Parameters
sampleThe sample of the desired pixel.
lineThe line of the desired pixel.
bandThe band of the desired pixel.
Returns
double The exposure duration for the desired pixel in seconds.

LineRate

@TODO Add a way to account for the padding described above. Push frame cameras handle this by having a separate exposure duration member that can be set by individual camera models. Then, if the exposure duration member is not it's default value (0) return it instead of the line rate.
