/* CRISM VNIR Sampling Wavelength Table                                     */

/* The CRISM VNIR spectrometer has smile, so a given row is not at constant */
/* wavelength bit varies by a little more than a wavelength bin across the  */
/* range of spatial pixels.  It is convenient for users of the CRISM data   */
/* to be able to do calculations assuming a given row is at a constant      */
/* wavelength.  This table gives a standard set of wavelengths to use for   */
/* such approximations.  Each wavelength in this table is an average of the */
/* wavelengths in a single row for columns 260-359.                         */

/* The sampling wavelength has two uses.  The unbinned VNIR columns 260-359 */
/* represent a part of the field of view with less than 1 nm smile, and     */
/* within that part of the field of view, the sample wavelength values are  */
/* in error by less than half a nm.  Our pixels are separated by about      */
/* 6.55 nm center-to-center, so half a nm of error is negligible for many   */
/* purposes.  Therefore, many analyses may proceed ignoring the smile, if   */
/* they operate only on columns 260-359.  This is particularly useful for   */
/* atmospheric analyses.  The second use of the sampling wavelength is as a */
/* standard set of wavelengths for nearest-neighbor wavelength resampling   */
/* of the entire field of view.  This is useful for analyses (such as       */
/* broad mineralogical features in spectral regions without atmospheric     */
/* absorption lines) that are not sensitive to half a pixel (about 3.3 nm)  */
/* of wavelength error.  The fact that the resampled wavelengths are correct*/
/* in columns 260-359 is helpful for the user to evaluate the effect of the */
/* resampling error in the rest of a given image.                           */

/* Related CDRs: The WA level 4 CDR gives the actual center wavelength for  */
/* each pixel, including smile.  The RW level 4 CDR gives the resampled     */
/* wavelength for each pixel.                                               */
/* The PS level 4 CDR gives the row number of the Zone 0 sampling           */
/* wavelength used by a pixel minus the row number of the pixel.            */
/* The zone 0 sampling wavelengths are given in the SW level 6 CDR.         */
