4.67 migsp 2.6
mical 1.4
4Ia 1B 4E 3I 6.1

Bug fixes:
- L1b products generated with wrong "NUM_DSR" value in the SPH; in particular this value differs by one unit from the "TOT_SCAN" value, while the two should be the same.
- Violation of the shared memory area of PFHS. PFHS performance is seriously affected, because too many manual re-starts become necessary.
