rsr_driver with --xlines sometimes creates bad fits

[teuben]

Example of problem in 104790:

 SLpipeline.sh obsnum=104790 xlines=110.7,0.1     ok
 SLpipeline.sh obsnum=104790 xlines=110.7,0.15    bad
 SLpipeline.sh obsnum=104790 xlines=110.7,0.2     bad
 SLpipeline.sh obsnum=104790 xlines=110.7,0.25    bad
 SLpipeline.sh obsnum=104790 xlines=110.7,0.3     ok
 SLpipeline.sh obsnum=104790 xlines=110.7,0.4     ok

the driver version of the script will show large positive and/or negative components. the rsr_sum is ok, as it does not use the xlines concept. @dsancheza

it seems the logic is reversed when the window is blanked. It will try and use the xlines= section of the spectrum when that band was blanked (e.g. via badcb=), instead of not using it.

To clarify: the xlines= keyword in the pipline becomes a --exclude keyword for rsr_driver

With the fix in rsr_driver and adjusting the threshold parameters as need be, this seems solved.
