Explorer POTA Mast replacement sections

For the POTA33, replacement sections 15-18, what is the outside diameter of section 15?
Thank you

@Tom_Crow . I don’t have outside diameters. When choosing replacement pieces this is the information available:

It is extremely important to ensure that you are counting the mast sections correctly, otherwise you may end up purchasing the wrong mast section. Sections are counted from bottom to top, with the outer casing (the orange outer shell of your mast) being considered the first section.
