Both pcompos and pcomb mess with the HDR header. Also, what you are doing here:
echo "VIEW= -vta -vh 180 -vv 180 -vp 0 0 0 -vd 1 0 0 -vu 0 0 1" > output_masked2.hdr is overwrite HDR image output_masked2.hdr with just the view string. You need to edit this image in a text editor and put a full VIEW= line back in. If you're happy using vim, then you could try Radiance's vinfo.
