% routine to plot ship board lat & lon assuming
% data is stored in columns 3 and 2 of the matrix "d" of ship.mat 

% Note: this routine is called by "atsee" pull down menu 

% load the data matrix in "ship.mat" file
  exi=exist('d');
  if exi==0;
    load ship;
  end;

% plotting ship track with quick clean
% user needs to edit lines below to specify reasonable ranges
% put down a base map with bathymetry
  id=find(d(:,3)>39&d(:,3)<43);
  d(:,2)=-1*d(:,2);
  id2=find(d(id,2)>-71&d(id,2)<-65);
  plot(d(id(id2),2),d(id(id2),3),'r.','markersize',10);
