[edit] VIMS Radiometric Calibration

• Overview of Radiometric Calibration

The application vimscal applies the dark current and flatfield correction to the input VIMS cube. vimscal requires ingestion into ISIS3 (vims2isis) and spiceinit (Level 0 processing)

Notes:

• By default, the output calibrated image cube will be in I/F Units and 32-bit for precision.

• All ISIS3 applications default to 'Tile' for output, regardless of the input file format

Example: vimscal from=v1514302573_1_ir.cub to=C1514302573_1_ir.cub

 vimscal from=v1514302573_1_vis.cub to=C1514302573_1_vis.cub

Sample image (v1514302573_1) is a VIMS observation of Titan [Sequence_Id=S17; Observation_Id=VIMS_019TI_HDAC001]

IR Portion: Samples=64 x Lines=64 x Bands=256

VIS Portion: Samples=64 x Lines=64 x Bands=96
