Error in SuperIndividuals when DistributionMethod = "HaulDensity" #87

Closed arnejohannesholmin closed 10 months ago

arnejohannesholmin commented 3 years ago

In the function SuperIndividuals when DistributionMethod = "HaulDensity" and the variable Beam in StoxAcousticData has more than one unique value in the same stratum, the Abundance distributed to each super-individual will be reduced, leading to under-estimation of the abundance.

This problem may occur if there are more than one vessel operating in a stratum, and these vessel have different number of beams in the echosounder.

The user can avoid this problem by translating Beam in the table Beam of StoxAcousticData so that the beams have a common ID. Use the functions DefineTranslation and TranslateStoxAcoustic to do this.

This was fixed in StoX v3.4.0 (2022-03-30).
