Frequency of DAC FID pairs with a frequency > 10000

Frequency of DAC FID pairs in AIS Message 6

These are the frequencies of DAC FID pairs in AIS Message 6 in data coming over AISHUB.  1586084 messages were recorded and analysed with R. With the pages from Arundalegpsd and VT-Explorer a guess was made about the content of some of these messages.

Many messages have seemingly non documented DAC FID pairs.

What follows are a pie chart of the messages with a frequency > 10000 and a table of all recorded DAC FID pairs.
