 Hello, my name is Alexander.

 I'm not able generate atmospherically corrected image from the band 3 of
 TM / Landsat 5 using i.atcorr.

 No error occurs during the process, however, the output image appears to
 be invalid and all pixels are NULL value.

 The input image is converted to the same band reflectance at the top of
 the atmosphere. The conversion was made by the module r.mapcalc.

 I'm using version 6.4.2 of the GRASS GIS and working through the graphical
 interface.

 My OS is Windows Vista Business SP2.

 Attached I am sending the *. MTL and basic metadata of the raster output
 i.atcorr (r.info).
