Orbit 86328(15) - the first burn bulding the descent orbit DV1=9.3 m/s.
After burn altitude Hmin= 188.2 km, Hmax= 219.2 km.
Orbit 86329(16) - the descent orbit second impulse DV2=10.4 m/s.
After burn altitude Hmin = 158.9 km, Hmax= 218.5 km.
Orbit 86331(02) - the final braking impulse until fuel supply is fully
consumed value DV3=28 m/s.
