[vsnet-alert 3984] Re: On Munidos error

["William S G Walker" <astroman@voyager.co.nz>]

Hi,

Actually the result was out by 36524 days, which is a recognisable number.
But on checking the fractional part I see that was out by +0.00059 days,
which is  about 51 seconds and doesn't seem related to anything.

Regards,
Stan
