Re: [Paparazzi-devel] IR_RollOfIrs and IR_PitchOfIrs

[Antoine]

Hi Doni

This macro is in airframe.h ( for example /paparazzi3/var/Twin1/airframe.h )
It is generated from the parameters stored in the airframe config file ( 
for example paparazzi3/conf/airframes/twinstar4.xml ).
This is needed to adapt to the different hardware mouting possibilities 
of the infrared sensor ( if its axis are aligned with aircraft or at 45 
degres etc...)

A+
