    Oblateness calculation given observer's latitude
    From: Ed Popko
    Date: 2018 Jan 29, 11:23 -0800

    Can someone point me to references that show how earth's oblateness is computed from an observer's latitude? It is a refinement for clearing lunar distances.

    I find many references stating oblateness it is not considered by this clearing method or another. And comments that, at times, it is such a smal correction it is ignored.

    But I never see a formula or how it is computed.

    Thanking you in advance ..
