subduction zone with dual polarities

[michaelchin]

This bug was reported by Sabin and is a part of #183.

I tried to reproduce the bug. The steps I had taken

• installed GPlately "update-data-download" branch
• run https://github.sydney.edu.au/EarthByte/EarthByteWorkflows/blob/pacific-maps/Maps/GPlately_orthographic_maps.ipynb

I don't see the subduction zone with dual polarities.

The screenshot below was provide by Sabin. I put the screenshot here for comparison purpose.

I had made another attempt to reproduce the "dual polarities" bug with the latest Muller2019 model and latest gplately code. The bug did not show. See the screenshot below.

I guess this "dual polarities" bug must only happen with a particular version Muller2019 model and certain revision of gplately code. To reproduce this bug, I need to know

• which revision of gplately code was used
• a copy of the Muller2019 model files which was used

I will contact customer for the info listed above. Add "Pending" label for now.

I have sent the customer an email "Progress report - Issue #188: subduction zone with dual polarities". Waiting for the customer's response.

The client said "If the issue is not recurring, then we could park it until it resurfaces with the double polarity.". It seems the client is not unhappy with the idea of putting this issue on ice.
