http://www.bfxyz.nl/ |
|
Bfx_Help2 informs about unit (e.g. meter to
yard) conversions BfX supports |
|
|
|
|
|
Bfx_Help2 also informs which drag functions can
be used |
|
|
|
|
|
|
|
Other worksheets will elaborate on how to use
these features |
|
|
|
|
|
|
|
To use BfX_Help2(): create a column with
values from 0 … 90 (or so) and then refer to a cell with BfX_Help2(cell to
the left) |

=======Bfx_Help2(0,1,2 ...) specifies supported
units and drag functions======== |
|
|
4 |
Use BfX_Help(0,1,2, ...) for help on BfX
ballistic and other functions |
|
|
|
5 |
==============================BfX_Help2(0,1,2
...)============================== |
|
|
6 |
BfX_Help2 lists available input and output
units as well as supported drag |
|
|
7 |
functions. Units and functions must be
specified in abreviated form, lower case |
|
|
8 |
without spaces and other blanks. If no units
are specified, the metric standards |
|
|
9 |
are used. eg
BfX_D("in";740;1000;"yd";0,22;"g7") calculates
the drop |
|
|
|
10 |
in [inches] for a bullet of 740 [m/s] (units
omitted) at a distance of |
|
|
|
11 |
1000 [yards] with a G7 ballistic coefficient of
0,22 |
