Dear,

Second issue. When I use mblist to export data, I use the follwing expression

mblist -I "$file" p.mb57 -MA -ONXYZBGgcH.sj.d 

It seems I cannot find the flag G for flat bottom grazing angle (degrees), by reading the datagrams.
I searched in datagram N, the BeamPointing angle, but the values are different. Where should I look?

Thanks in advance

I have a strange issue.

In some .all files datagram N has no datagram.Counter, but datagram.PingCounter
In some other files (also datagram N) it's the excact opposite.

Any ideas?

For starters, thanks for this real great package.

I have troubles with the Acrosstrack and alongtrack distance.
My .all files has the following datagram structure
P --> NXY, NXY, NXY, NXY --> P...

In other words, I have a P datagram followed by 4 N,X,Y datagrams. This is a multimbeam System EM 2040C. Thus, in those 4 N,X,Y, we have mutlibeam left-right head in the 2 datagrams.
Or if I rephrase differently, 1 P datagram 2 pings (left right).

Now, I get from P datagram lat,lon which I convert to UTMX,UTMY
From every X datagram, I get
x1=datagram.AlongTrackDistance
y1=datagram.AcrossTrackDistance

Thus, this specif datagram has coordinates,
new_x=UTMX+x1
new_y=UTMY+y1

If I plot them, I can see that the first two X datagrams are plotted correctly, the second pair of X datagrams appears bend.
