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 */ /* accurate 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. */ OBJECT = FILE /* The time string in the file name will increment if there is a change in */ /* VNIR standard sampling wavelengths */ ^TABLE = "CDR6_1_0000000000_SW_S_0.TAB" RECORD_TYPE = FIXED_LENGTH RECORD_BYTES = 13 FILE_RECORDS = 480 OBJECT = TABLE NAME = "CRISM STANDARD SAMPLING WAVELENGTH TABLE" INTERCHANGE_FORMAT = "ASCII" ROWS = 480 COLUMNS = 2 ROW_BYTES = 13 DESCRIPTION = "CRISM Standard sampling wavelength table" OBJECT = COLUMN COLUMN_NUMBER = 1 NAME = ROWNUM DATA_TYPE = ASCII_INTEGER START_BYTE = 1 BYTES = 3 DESCRIPTION = "detector row number (0-479)" END_OBJECT = COLUMN OBJECT = COLUMN COLUMN_NUMBER = 2 NAME = SAMPL_WAV DATA_TYPE = ASCII_REAL START_BYTE = 5 BYTES = 7 DESCRIPTION = "Standard sampling center wavelength in nm" UNIT = "NM" END_OBJECT = COLUMN END_OBJECT = TABLE END_OBJECT = FILE END
