    Re: Pub. 249 origins and history
    From: David C
    Date: 2021 May 10, 00:37 -0700

    From Cotters's PhD thesis:

    Hutchings, Lieut C H USN (1942) Tables of Computed Star Altitudes  and True Azimuths. Proc of US Naval Institute vol 68 Washington.

    Cotter also gives a reference to a 1946 paper that may be of interesst when researching 249 and 1618 but I cannot copy and paste so will have to tyoe it manually if anyone is interested.......
