Q1: Please see the formula in red circle on [http://libcoll.mpiwg-berlin.mpg.de/libcoll_zogilib?fn=/permanent/library/H9ZYCGQ0/pageimg&pn=625&ws=1&wx=0.2082&wy=0.3728&ww=0.7195&wh=0.0694&mk=0.365/0.3994 attached image 0624.JPG (754,453 bytes)]. Could you please give us some suggestion that how to mark up it? 

A: Please type:
{{{F G = <sqrt>2 _rx_ - _xx_</sqrt> X <sqrt>2 _rx_ - _xx_</sqrt>}}}

Please note: Always use "=" for the character after F G.

Q2: Please see the [http://libcoll.mpiwg-berlin.mpg.de/libcoll_zogilib?fn=/permanent/library/H9ZYCGQ0/pageimg&pn=612&ws=1&wx=0.0596&wy=0.1399&ww=0.7027&wh=0.0827&mk=0.1295/0.1726 second line on the image file 0611.jpg]. There are lines above the information "{{{DE<^>3</^>}}}" and "{{{AC<^>3</^>}}}". Please advise us how to express the lines.

A: Please type:
{{{<ol>DE</ol><^>3</^> ad <ol>AC</ol><^>3</^>, ita Cohærentia ...}}}

The attached image 0624.jpg corresponds to [http://libcoll.mpiwg-berlin.mpg.de/libview?url=/mpiwg/online/permanent/library/H9ZYCGQ0/pageimg&start=621&pn=625&mode=imagepath p.625] in ECHO, and 
0611.jpg corresponds to [http://libcoll.mpiwg-berlin.mpg.de/libview?url=/mpiwg/online/permanent/library/H9ZYCGQ0/pageimg&start=601&pn=612&mode=imagepath p.612] in ECHO.)

Q3: This book is full of forms and formulas so that the keying speed is very slow. The speed of this book is 63% of the speed of normal books. Thus we need to charge for it at a higher price as follows: 0.943 ÷ 0.63 = $1.50/1000 characters

A: We fully acknowledge the additional work for keying formulas and we therefore agree with your proposal. We herewith would like to confirm the price of $1.50/1000 characters for this book.

== 3.  Analysis of the Result ==

=== Findings ===
The character recognition is high as usual. However, the few Greek words in the text have been replaced by a series of "?". See [http://libcoll.mpiwg-berlin.mpg.de/libcoll_zogilib?fn=/permanent/library/H9ZYCGQ0/pageimg&pn=164&ws=1&wx=0.2156&wy=0.2673&ww=0.7128&wh=0.0778&mk=0.4753/0.303 here]. (transcribed as
<p>Vocatur hic â Meridiano rece$$us, _Declinatio, Variatio, De-_
_viatio_, ????????????.</p>)

The subscript tag <_> was used consistently for superscript.

In one case, a root was tagged with the non-existent <sp>-tag ([http://libcoll.mpiwg-berlin.mpg.de/libcoll_zogilib?fn=/permanent/library/H9ZYCGQ0/pageimg&pn=492&ws=1&wx=0.225&wy=0.5885&ww=0.718&wh=0.062&mk=0.7145/0.646 p 478]):
{{{
plano borizontali _E C D_. erit Cobærentia ba$eos ad eam $egmenti in
ratione ba$eos _A O B_ ad eandem {_A O B X E F X <sqrt>E F</sqrt>/A F X <sp>A F</sp>_}.</P>
<P>Vocentur A O = _a_. O B = _b_. F A = _d_. E F = _x_.</p>
