Hi,
We've noticed some strange "ghost" luminaires in Radiance 4.2 (nothing to do 
with Halloween yesterday).
I've uploaded a file with a sample .pic file and the files used to generate it 
at http://upload.iesve.com/downloads/radiance_issues/ghost_luminaire.zip

As you can see from the .pic file there's a "ghost" luminaire to the centre 
left of the image which appears to be generated by the luminaire visible in the 
centre of the image (turning off the others while leaving it on still shows the 
ghost while vice-versa doesn't). Rotating the view to the right also removes 
the "ghost".
The commands we're running to generate the image are as follows:

oconv -f Monday.map Monday.rad > ghost_lum.oct
rpict -w -t 2 -vtv -vp 6.300 8.100 1.800 -vd -2.800 -3.600 0.000 -vu 0 0 1 -vh 
80.000 -vv 60.000 -x 1600 -y 1600 -x 64 -y 64 -ps 6 -pt 0.100 -pj 1.0 -dj 0.350 
-ds 0.300 -dt 0.250 -dc 0.350 -dr 2 -dp 128 -st 0.500 -ab 2 -aa 0.150 -ar 64 
-ad 128 -as 64 -lr 6 -lw 0.005 -av 0.000 0.000 0.000 -af temp.amb ghost_lum.oct 
>amb.raw
rpict -w -t 2 -vtv -vp 6.300 8.100 1.800 -vd -2.800 -3.600 0.000 -vu 0 0 1 -vh 
80.000 -vv 60.000 -x 1600 -y 1600 -ps 6 -pt 0.100 -pj 1.0 -dj 0.350 -ds 0.300 
-dt 0.250 -dc 0.350 -dr 2 -dp 128 -st 0.500 -ab 2 -aa 0.150 -ar 64 -ad 128 -as 
64 -lr 6 -lw 0.005 -av 0.000 0.000 0.000 -af temp.amb ghost_lum.oct 
>ghost_lum.raw
pfilt -m 0.25 -x /2 -y /2 ghost_lum.raw >ghost_lum.pic

If anyone has a few minutes to run this image on their systems & let me know if 
the "ghost" luminaire also appears for you it would be most appreciated (I'm 
using Radiance HEAD built from source on Windows 7 SP1).

Thanks,
