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 270-369. */ /* The sampling wavelength has two uses. The unbinned IR columns 270-369 */ /* 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 270-369. 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 270-369 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_9_0947778566_SW_L_3.TAB" RECORD_TYPE = FIXED_LENGTH RECORD_BYTES = 14 FILE_RECORDS = 480 OBJECT = TABLE NAME = "CRISM STANDARD SAMPLING WAVELENGTH TABLE" INTERCHANGE_FORMAT = "ASCII" ROWS = 480 COLUMNS = 2 ROW_BYTES = 14 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 = 8 DESCRIPTION = "Standard sampling center wavelength in nm" UNIT = "NM" END_OBJECT = COLUMN END_OBJECT = TABLE END_OBJECT = FILE END
