1316	EXPTIME and MJD_OBS don't make it to stamps	bills	bills	"The way ppstamp copies the concepts from input to output causes some data to be lost.

Doing 
pmConceptsCopyCell(outCell, inCell);

gets EXPTIME and MJD_OBS written  to the output correctly for skycells but the size of the image gets copied as well so all pixels get set to zero. 

And at any rate the concepts still don't get set right for chip stage stamps.
