+Statistics processing scripts (README)
+
+This directory contains a number of scripts for use with the filegen
+facility. Those files ending in .awk are for the Unix awk utility, while
+those ending in .sh are for the csh utility. Normally, the summary.sh
+script is called from a cron job once per day. This script processes the
+daily loopstats, peerstats and clockstats files produced by the daemon,
+updates the loop_summary, peer_summary and clock_summary archive files,
+and deletes the daily files.
+
+In the case of the Austron 2201A GPS receiver, the clockstats file
+contains a wealth of additional monitoring data. These data are summarized
+and writted to the clock_summary file, then a series of special files are
+constructed for later processing by the S utility.
+
+The summary.sh script invokes a number of awk scripts to actually produce
+the data. This may result in multiple scans of the same input file.
+The input file is deleted after processing. In fact, the shell scripts will
+process all input files found of the correct type in chronological order,
+deleting each one as it is scanned, except the current day file.
+
+The summary.sh script can produce input files for the S utility, if it
+is found on the search path. This utility makes PostScript graphs of the
+loopstats data for each day, as well as various statistics produced by
+the Austorn 220aA GPS receiver. The S utility is automatically run
+as a background job. Its control files have the .S extension.
+
+The psummary.awk script can be used to scan the peer_summary file and
+construct an historical reprise of the daily summaries.
+
+The file formats are documented in the README.stats file and in the
+scripts themselves. Further detail on the radio clock ASCII timecode
+formats and related data are in the README.timecode file.

+Statistics file formats (README.stats)
+
+The xntp3 daemon can produce a variety of statistics files which are
+useful for maintenance, evaluation and retrospective calibration
+purposes. See the xntpd.8 man page for instructions on how to configure
+this feature. Since these files can become rather large and cumbersome,
+they are ordinarily reduced to summary form by running the summary.sh
+shell script once per day, week or month, as appropriate. There are
+three file collections presently defined: peerstats, loopstats and
+clockstats, each of which is described in this note.
+
+peerstats
+
+The following data are collected in the peerstats files. The files are
+reduced to summary data using the peer.sh shell script. See the peer.awk
+script for further information. A line in the file is produced upon
+reception of each valid update from a configured peer.
+
+ 49236 30.756 140.173.96.1 9474 0.000603 0.37532
+
+ 49236 modified Julian day number
+ 30.756 time of day (s) past midnight UTC
+ 140.173.96.1 peer identifier (IP address or receiver identifier)
+ 9474 peer status word (hex) (see NTP specification)
+ 0.000603 offset (s)
+ 0.08929 delay (s)
+ 0.37532 dispersion (s)
+
+loopstats
+
+The following data are collected in the loopstats files. The files are
+reduced to summary data using the loop.sh shell script. See the loop.awk
+script for further information. A line in the file is produced at each
+valid update of the local clock.
+
+ 49236 11.897 -0.000004 -35.9384 0
+
+ 49236 modified Julian day number
+ 11.897 time of day (s) past midnight UTC
+ -0.000004 time offset (s)
+ -35.9384 frequency offset (ppm)
+ 0 phase-lock loop time constant
+
+clockstats
+
+The following data are collected in the clockstats files. The files are
+reduced to summary data using the clock.sh shell script, which also
+updates the ensemble, etf, itf and tdata data files as well. See the
+clock.awk, ensemble.awk, etf.awk, itf.awk and tdta.awk scripts for
+further information. A line in the file is produced at each valid update
+received from a configured radio clock. Data are at present recorded for
+several radios. The first part of each data line is similar for all
+radios, e.g.:
+
+ 49234 60517.826 127.127.4.1 93 247 16:48:21.814
+
+ 49234 modified Julian day number

+ 127.127.4.1 receiver identifier (Spectracom 8170/Netclock-2)
+ 93 247 16:48:21.814 timecode (format varies)
+
+In the case of the Austron GPS receiver, a good deal of additional
+information is extracted from the radio, as described below. The formats
+shown consist of one line with all the fields shown in order. The
+timecode formats specific to each radio follow. See the file
+README.timecodes for detailed information on the timecode formats used
+by these radios.

+
+Depending on the installed options, the Austron 2200A/2201A recognizes a
+number of special commands that report various data items. See the
+refclock_as2201.c source module for a list of the commands used. These
+data are collected only if the following line is included in the

+Radio Timecode Formats (README.timecodes)
+
+Following are examples of the serial timecode formats used by various
+timecode receivers as given in the instruction manuals. These examples
+are intended only for illustration and not as the basis of system
+design. The following symbols are used to identify the timecode
+character that begins a subfield. The values given after this symbol
+represent the character offset from the beginning of the timecode string
+as edited to remove control characters.
+
+C on-time character (start bit)
+Y year of century
+T time of day
+D day of year or month/day
+A alarm indicator (format specific)
+Q quality indicator (format specific)
+<LF> ASCII line feed (hex 0a)
+<CR> ASCII carriage return (hex 0d)
+<SP> ASCII space (hex 20)
+
+In order to promote uniform behavior in the various implementations, it
+is useful to have a common interpretation of alarm conditions and signal
+quality. When the alarm indicator it on, the receiver is not operating
+correctly or has never synchronized to the broadcast signal. When the
+alarm indicator is off and the quality indicator is on, the receiver has
+synchronized to the broadcast signal, then lost the signal and is
+coasting on its internal oscillator.
+
+In the following uppercase letters, punctuation marks and spaces <SP>
+stand for themselves; lowercase letters stand for fields as described.
+Special characters other than <LF>, <CR> and <SP> are preceded by ^.
