[Clas12_verystrange] gcard

Hi,

In the document

https://clasweb.jlab.org/wiki/images/4/4c/Pre-release4a.7.5.pdf

it says to "use gcard on the farm".

I grabbed the gcard located on ifarm at

/group/clas12/gemc/4a.2.0/clas12.gcard

is this the right one?

When I run gemc it is taking from 4a.1.0 :
* beamline
* ft
* torus

and uses 4a.2.0 for the other detectors.
Is this expected?

I threw 100 K Lambda events where
Lambda -> p pi- (64%) and
Lambda -> n pi0 (36%)

The scattered electron angle was required to be between 1 and 5 degrees.

When I look at the output I get

* No forward tagger events

* 100 events with pid=0 and charge=1.

* 6 events with charge = 0 (all identified as pid=0)

* 22 protons

* 14 pi+

* 5 pi-

I must be doing something wrong :(

Take care,
Michael
