Thank you for your contributions to Wikipedia. It appears that you copied or moved text from Spherical Earth into another page. While you are welcome to re-use Wikipedia's content, here or elsewhere, Wikipedia's licensing does require that you provide attribution to the original contributor(s). When copying within Wikipedia, this is supplied at minimum in an edit summary at the page into which you've copied content, disclosing the copying and linking to the copied page, e.g.,. It is good practice, especially if copying is extensive, to also place a properly formatted copied template on the talk pages of the source and destination. The attribution has been provided for this situation, but if you have copied material between pages before, even if it was a long time ago, please provide attribution for that duplication. You can read more about the procedure and the reasons at Copying within Wikipedia. Thank you. Dr.  K.  17:59, 1 August 2019 (UTC)
