TriCCS data are stored as 3D FITS cubes containing multiple frames. Enter the desired exposure time per frame. As in the TriCCS observation GUI, the actual exposure time is automatically rounded down to an integer multiple of 0.010168 sec. The minimum exposure time is 0.010168 sec (approximately 98 fps). A single FITS cube has been tested with up to 3000 frames; cubes containing more than 3000 frames may not be saved correctly.
