function dpixcreate
Creates a dead pixel list of X using a magic threshold. Boxsize defaults to 3 and gives the radius of the running boxcar used. NPASS defaults to 3 and gives the number of passes used.
Syntax
result = dpixcreate(X, THRESHOLD [, BOXSIZE [, NPASS]])
Arguments
| X: | On this array the dead pixel list will be created |
| THRESHOLD: | Sensitivity of the algorithm (use 5 for a start) |
| BOXSIZE: | Optional, the size of the square box for comparing pixel values (default: 3) |
| NPASS: | Optional, number of iterations |
