Hello Sarah,
When the innermost arc is January, so is the outermost. When the
innermost arc is July, the outermost is also July. But a glance at
the graphics produced by spin.exe indicates the normal monthly
sequence reads from outside to inside.
Best wishes,
Mac
From Fer's recent message:
>> In my program Spin you may choose between inner circle as january or as
july.
>>This overcomes a litlle the problem of the gnomon length.
From readme2.doc Zonwvlak:SPIN .EXE : calculates a horizontal
azimutal sundial and writes thepoints to a file <name.RLT>. This
file can be drawn on the screen withthe program SCRPLT.EXE.The
months of the date-scale are in circles. The outmost circle can
bejanuary first or july first.The program works for latitudes
between 25 and 66.5 degrees and between
-25 and -66.5 degrees.
Now which is it, innermost, or outermost?
