    Re: the term "Latitude by account" means??

    Alan,

    Can you post an image of the page in Hansen's tables where it refers to Latitude by account. I do not have my copy with me here in Florida. As I recall when doing the initial look-ups using Latitude and Declination you will be using the DR Latitude and the Declination for the time of the observation. Precision is not critical here so the nearest whole Latitude and Declination will often be good enough for selection of the Key Table. Visual interpolation using the DR Latitude and exact Declination for the time of observation will improve the Key Table section for more precise ex-meridian corrections which is how I do it.
