Plotting great circles for points on map

Hi,
I have plotted data points on map which are connected by great circles. Code and output figure are attached;

gmt begin Map png
gmt basemap -JM4i -R130/160/30/60 -Bxa5 -Bya5 -BWESN
# plot points as star symbol
gmt psxy -JM4i -R130/160/30/60 -Sa0.14i -Gbrown << EOF
132	54
158	56
135	40
150 	45
EOF
# draw great circle for points
gmt psxy -JM4i -R130/160/30/60 -W1.5,blue << EOF
132	54
158	56
>>
135	40
150 	45
EOF
gmt end 

The great circles in figure may look like simple lines and have no enough curvature.

Is there a way by which user can increase curvature of great circles in GMT?

Thanks for help.

That looks about right to me. If you want something that looks like exaggerated great circle segments look into plot -W+s on how to plot Bezier splines.

Better link for Bezier splines:

The Cookbook on -W scroll down to +s.

Many thanks for your solution, it solved issue as per my need.
