Description Removes the noise known as "streak" from THEMIS spectral images. Streak only occurs in approximately 1% of the data and may only be visible in bands 1 and 2 of emissivity images.
Arguments and Return Values Arguments: A rectified, deplaided, autoradcorred, spectral radiance THEMIS cube Return Value: The spectral cube cleaned
Usage Syntax: destreak(data,ignore,bandlist) 'data' is a 10 band float THEMIS radiance cube whose null-data value is -32768. 'ignore' is the ignore value for the image default is -32768 'bandlist' is a list of the contained bands in the x direction, default is 1//2//3//4//5//6//7//8//9//10
Examples dv> a 324x1499x10 array of float, bsq format [19,427,040 bytes] dv> b = destreak(a) 324x1499x10 array of float, bsq format [19,427,040 bytes]
