What icon sizes are important for your Win RT app?

The are quite a couple of icons that you can set, though not all of them are absolutely required.
For the tile we have the following logo sizes. I also created the example of an app I'm working on.
The main tile requires a logo of 150x150 pixels.

Then we have a wide logo that's only required when you want your app to be visible with a wide logo on the Start screen. When you use it, the size has 310x150 pixels. That's two tile logo's + a 10 pixel margin.
