| Description: The shutter timing correction applied during the exposure correction step, measured in milliseconds. This offset accounts for the finite time required for the shutter to fully open and close, which affects the actual exposure time of the image. The offset values (2.75 ms for NAC, 2.67 ms for WAC) were determined through ground calibration and represent the mean delay across the field of view. These values are used in conjunction with temperature-dependent shutter offset files that provide position-specific corrections across the detector. |
