//
//  This task tries to identify the starfield from the
//  MMcRunHeader container and tries to identifies it. If it is known
//  (eg. Crab) the fixed build in pixel numbers are used as blind
//  pixels.
//
//  Implemented star fields (for the MAGIC camera only):
//   - Crab: 400, 401, 402, 437, 438, 439
//
//  Input Containers:
//   -/-
