[guide-user] problem with adding OAG chip

Hello all,

I tried to add a guiding chip to an existing camera in CDDS.NAM and also in 
CCDS.NAD (the german counterpart). But without success.

I raised the numer of cameras by 1 at the top of the files (201 in my case). I 
copied the existing camera entry (Moravian G2-8300)

Moravian G2-8300                 KAF-8300     5.4      5.4	3358  2536  212

and gave it a new ID which wasn't used: 215. Then I added the following 
parameters:

0,.9,.31,.23,1936,1096 which means that the guiding chip (a ZWO ASI290 Mini in 
the Moravian Off Axis Guider) is in the middle above the main chip and the guider 
chip has 31% of the width and 23% of the height of the main chip. And the number 
ot the pixels of the ASI290 Mini is 1936 x 1096.

So the complete line of the new camera definition looks like this (without the 
line break):

Moravian G2-8300 + ASI290Mini    KAF-8300     5.4      5.4	3358  2536  215 
0,.9,.31,.23,1936,1096

But whatever I do, when choosing the new camera in Guide, the ccd frame is shown 
without the guiding chip and it's surrounding circles. I even tried the values 
form several SBIG guiding chips, no success.

Any help is appreciated.
