****** COMPATIBILITY CHANGE ******** | 
| 1648 | 
  | 
Fixed long-standing bug in source.cal, which caused it to produce | 
| 1649 | 
  | 
reversed anisotropic photometric distributions due to the | 
| 1664 | 
  | 
Modified -c option to rtcontrib so it can take a number of input | 
| 1665 | 
  | 
rays to average over, rather than only produce a single accumulated | 
| 1666 | 
  | 
record (which can now be done with -c 0). |
