sd.linefinder.set_options  Function
5.1.6 Set the parameters of the line finding algorithm
Description
This method is used to set the parameters of the line finding algorithm. There
are six parameters that can be set by this method. See description of this
object for details about parameters.
Note that, for bad baselines, threshold should be increased, and avg_limit decreased (or even switched off completely by setting this parameter to 1) to avoid detecting baseline undulations instead of real lines.
Arguments
Inputs 
 
threshold 
 A single channel S/N ratio above which the channel is
considered to be a detection.  
 allowed:  float 

 Default:  sqrt(3) 

min_nchan 
 A minimal number of consequtive channels, which
should satisfy a threshold criterion to be a detection.
 
 allowed:  integer 

 Default:  3  
avg_limit 
 A number of consequtive channels not greater than this
parameter can be averaged to search for broad lines.
 
 allowed:  integer 

 Default:  8 

box_size 
 A running mean/median box size specified as a fraction
of the total spectrum length.
 
 allowed:  float 

 Default:  0.2 

noise_box 
 Area of the spectrum used to estimate noise stats
 
 allowed:  float, string (’all’ or ’box’) 

 Default:  ’all’ 

noise_stat 
 Statistics used to estimate noise
 
 allowed:  string (’mean80’ or ’median’) 

 Default:  ’mean80’
