[GRASS-user] Problems with r.viewshed.cva

[Helmut Kudrnovsky]

>Module r.viewshed fails, ...

['r.viewshed', '--q', 'observer_elevation=1',
'input=elev_lid792_1m at PERMANENT',
'refraction_coeff=0.14286',
'coordinates=638736.69107769,220612.66221008', 'memory=500',
'max_distance=-1', 'output=vshed_1\r',
'target_elevation=1.75'] ended with error

'output=vshed_1\r' seems to cause troubles.

?
