5.1.7 sd.simplelinefinder - Tool

Simplified line finder tool for single-dish spectrum
Description

A simplified class to search for spectral features. The algorithm assumes that the bandpass is taken out perfectly and no spectral channels are flagged (except some edge channels). It works with a list or tuple rather than a scantable and returns the channel pairs. There is an optional feature to attempt to split the detected lines into components, although it should be used with caution. This class is largely intended to be used with scripts.

The fully featured version of the algorithm working with scantables is called linefinder.

Methods

channelRange	Convert supplied velocity range into the channel range
find_lines	Search for spectral lines in the spectrum
invertChannelSelection	Invert channel range selection
median	Return a median of the last spectrum passed to find_lines
rms	Return rms calculated during last find_lines call
writeLog	Write user defined string into log file
