    Here is a 2nd iteration plot using the rough plot fix position as the new assumed position. The error circle is a rough weather 2 nautical mile radius  50 % circle. As can be seen only 1 LOP falls within the circle and 2 LOPs are well outside the circle which has me thinking that there could be a problem LOP on this round of observations. I would have liked a fourth LOP added with an azimuth opposing the others.
