Jump to: navigation, search

Description

Create temperature to radiance look up tables by integrating the Planck function times the appropriate instrument filter function. This function works for THEMIS, ASTER, and TIMS

Arguments and Return Values

Arguments: Instrument

Return Value: An array containing the temperature to radiance look-up information for each spectral band

Usage

Syntax: make_temp_rad([themis][, aster][, tims])

Creates array of temperature and spectral radiance, weighted by filter response

Spectral radiance is in units of W cm-2 str-1 micron-1

Array is [nbands+1,ntemps], where x dimension is temp and n spectral radiances

Examples

dv> aster=make_temp_rad(aster=1)
.start temp = 100.0  end temp = 380.0 d temp = 0.5
nwaves = 401   ntemps = 561 nbands = 5
6x561x1 array of double, bsq format [26,928 bytes]

dv> tims=make_temp_rad(tims=1)
.start temp = 100.0  end temp = 380.0 d temp = 0.5
nwaves = 158   ntemps = 561 nbands = 6
7x561x1 array of double, bsq format [31,416 bytes]

dv> themis=make_temp_rad(themis=1)
Apparent file size: 11x4000x1
start temp = 100.0  end temp = 380.0 d temp = 0.5
nwaves = 4000   ntemps = 561 nbands = 10
11x561x1 array of double, bsq format [49,368 bytes]

dv> dump(aster[,550:])
