Unless I have missed something obvious, the problem described by Beatrice
with i.landsat.toar still exists?

I've tried both WinGrass 7.0.svn build 2013-11-24 and WinGrass 6.4.4svn,
revision 58275 (2013-11-24).

I've tested with a L8 and L5 scene (both with the new metadata file), using
'uncorrected' atmospheric correction method. I just chose the sensor type
and left everything else default.

Both command output (verbose) and r.info print zeros for Earth-sun
distance, Sun elevation, DN range, Calibration constants, DN to Radiance,
ESUN and Radiance to Reflectance values.

The output files give sensible reflectance values, but can I trust them
(i.e. the metadata file was read correctly and the right parameters were
used)? I haven't compared with Linux version.
