Dear Science and Astronomy friends, Vidur, Rathnaji, Dr. Anasji, Dr. Raghavan,

Thank you for comments and considerations, I do understand your concerns for
technical errors made in practical experimented by Vidur. Though there was a
technical error by Vidur to measure elongation, as he did not keep in mind to
check the (N=>S) line artificial horizon, and relied on that assumption. it may
be 5-6 degree out of line and makes a lot difference. also he should take
consideration of Latitude and position of SUN - about 2 degree north of equator
at that time. and my point to encourage him was that - My long experience of
study of - Astronomical engineering architecture and Temples of SUN and its
applications, I realised that what he was going to do was Principally correct,
and on that bases of Astronomical engineering architecture - all JANTAR MANTAR
are based and constructed and RAMYANTRA does work on same principal. Though he
should try again correctly again as some ones calculation (~43 degrees) was
incorrect and misleading.

More over for correction by spherical astronomical calculations , he need to do
a lot. Such and important books are now disappeared from the course work of
science - though some of translated old copies by UNIVERSITY GRANTH NIRMAN
BOARDS are available some where but now difficult to get because of copy right
laws. but some do hold photocopies over there. One of such good book is here
below.

thank for your reply, I should thank you all to encourage and guide all those
are participating in this field,

Dear Patelji
You have given very useful information about how little the the
elongation of venus has varied in the past several days. Any quantity
that passes through a maximum or minimum will always chage slowly
close to that maximum or minumum.
Vidurji has made a careful time measurement of the difference between
the setting times of the sun and venus. He has reported for March 27,
a time difference of 3h and 36m and 30s giving an equivalent angle of
~54 degrees. THIS HOW EVER is not the elongation as he had
originally assumed, not even the difference in RA of Venus and sun
(~43 degrees). Yet it was a very accurate measuremnt because he set
up his experiment very carefully! The elongation calculation itself
involved assuming the azimuths today. By tomorrow he will be able to
measure that as wellhopefully.
So by doing this experiment he has really understood nature of
projection effects. Nature works in far more interesting ways than
we initially assume. Vidurji, by reporting it in this forum has made
many more become aware of this which is the essence of a discussion
group.I hope you and your active group will also do this as you may
have clear horizons and report it.Unfortunately I donot have access
to clear horizons.
