    Right,  so you can extract log trigs to a second of arc accuracy, I
    thought that was what was wanted. Obviously a table that lists the
    values for each second would be 60 times as voluminous as table 33 and
    would probably allow interpolation to a 60th of a second which is  20
    inches on the ground, way too much accuracy for me.
