		+
		+	===Cleaning the time series===
		+	Currently the time series plots are cleaned or filtered using the hack-job method. These tasks are carried out with the ''clean_env_summary'' subroutine. Data are excluded from the plots with a variance tolerance and a crude outlier detector. the variance tolerance is some factor of the average variance of the time series, this prevents a noise time period from having all data excluded. Outliers are detected by fitting a line to segments of the time series, with any data farther from some tolerance from the line being excluded.
		+
		+	Since cleaning with this method is a hack-job I recommend only examining filtered time series in the context of the raw time series.
		+
		+	Both filtered and raw time series are created for the AVO web page.

−	The baselines are created with the ''baseplot'' script.	+	The baselines are created with the ''baseplot'' script. This script is a somewhat convenient wrapper for the ''make_env_summary'' and ''plot_time_series'' scripts. ''baseplot'' not only calls these two functions, but also organizes the file lists for input and gives multiple image formats as output.
		+
		+	Type ''-h'' for help:
		+	<pre>
		+	baseplot -h
		+
		+	Generate GPS timeseries plot update:
		+	This is the old AVO web-page script. It has been upgraded to do the
		+	specific task of making timeseries plots. The outputs are imgae files
		+	of the GPS baselines.
		+
		+	INPUTS:
		+	-regen : regenerate 1 year timeplot.
		+	-update : update an existing plot with todays data.
		+	-start [ymd] : start time for timeseriesi (default = today - 1yr)
		+	-stop [ymd] : stop time for timeseries (default = today)
		+	-dir [directory] : working directory (default = pwd)
		+	-sfile [file] : file with a list of .sum files to use
		+	-blist [file ] : file with baseline pairs SITE-SITE
		+	-s [site1] [site2]: stations for single baseline
		+	-c[lean] : clean up the timeseries w/ clean_env_summary
		+
		+	UPDATE can only be used with a directory where timeplots already exitst.
		+	If START and STOP are given REGEN is automatically used.
		+
		+	SFILE over-rides the date inputs; the SFILE will be used instead of
		+	creating a new one.
		+
		+	EX: baseplot -regen -dir ./dir_out
		+	This command creates a timeseries of the past year and puts the
		+	files in the directory dir_out.
		+
		+	baseplot -start 06jan12 -stop 06apr20
		+	This command will make plots of the specified dates in the current
		+	directory
		+
		+	baseplot -stop 07feb01
		+	This command will create a year long timeseries ending on Feb. 1, 2007
		+
		+	Updated Oct 2007, Tom Fournier
		+
		+	</pre>
		+
		+	*A major draw back of ''baseplot'' is that the function it uses to list the available .poscov files, only searches for ''AVO'' and ''alaska'' solutions.
