= release note : version guineapig++-0.6.1-b =


== all the keywords of the initial guineapig C version are now avalaible ==

i.e. : the following keywords have been implemented : do_size_log, load_event, do_coherent, do_cross, load_photon

=== keyword : load_photon === 

the input file is : '''photon.ini'''. The format is :
{{{
energy, xpos, ypos, zpos, vx, vy, helicity
}}} 

i.e. the same as for '''electron.ini''' or '''positron.ini''' with the helicity at the end.

=== keyword : load_events === 

the input file is : '''event.ini'''. The format is :
{{{
e, x,y,z,vx,vy,vz
}}} 

with the same units as for '''secondaries.dat'''


== load_beam : new possibilities ==

for load_beam = 3, the grid is computed from beam characteristics (sigma...) given in acc.dat.
However, a new possibility has been introduced : if the new keyword '''cuts_from_loaded_beam''' is set to 1, the cuts are computed from sigmas (sigx, sigy, sigz) of the actually loaded beams. These sigmas are computed as these beams were gaussian.

In addition, there are three other new keywords : '''cut_x_factor''', '''cut_y_factor''', '''cut_z_factor''', with default value : 3.0. 

The cuts will be so : 
{{{
cut_x = cut_x_factor*sigx
cut_y = cut_y_factor*sigy
cut_z = cut_z_factor*sigz
}}} 


Remark : the standard '''load_beam''' value are 0 (default) or 3 (PLACET format). '''load_beam''' = 1 or 2 are not available.

== minijets ==

The '''do_jets''' has been revisited and bugs fixed. The output file for minijets is : '''minijets.dat"
