For completeness, I list the procedural sequence that should be followed with the tables: (repeat for those who are interested, I can send you by email all tables for all relative bearings ad all LOS type)

Scenario: bearing-only TMA, track target with TA, ownship and target(submerged) in search phase.

i) Measure the Br at time 2 and 4. (target range is decreasing or increasing?)
ii) Recognize LOS type. (LAG, LEAD)
iii) Whit the Br measured at time 4 and relative target bearing measured at time 2 --> choose the corresponding table. (RelativeB+LOS+Br --> Table)
iv) Obtained the probable interval target range, seek a possible alignment of the points in the dotstack in the interval range. (Strip plotting)
v) If the probability is friendly, the target will not be far from the solution found. Otherwise you will fall into the 5% probability that the interval be wrong.
