Southern Sierra Passive Arrays			9 Jun 1996
1993 Deployment
Continuous Data @ 20 sps,  3 channels

CV-7	Volume 7	Days 254 - 262

File 1		Release notes:  SS93_Release_x.y
		254_262.readme
		254_262.wfdisc

File 2		Directories D254 D255 ... D262
		  containing waveforms
-------------------------------------------------------
Continuous data is organized in Day directories Dnnn.
A normal working environment,  in directory $DAYS,  would
contain:

SS93_Release_x.y
191_207.wfdisc  191_207.readme
208_218.wfdisc	208_218.readme
219_227.wfdisc  219_227.readme
228_236.wfdisc  228_236.readme
237_244.wfdisc  237_244.readme
245_253.wfdisc  245_253.readme
254_262.wfdisc  254_262.readme
etc...
D191/
D192/
...
D298/

The data is released in volumes containing about 1.5 gb, compressed.
It may be tar'ed in from tape to $DAYS one volume at a time,
	up to the capacity of the filesystem.

To make room for new data loads,  old day groups should be
removed:  rm -r D208 D209  ....

The directory structure will be maintained by the 'tar x  ...'
	process.
--------------------------------------------------------
To load a volume

setenv TAPE /dev/nrmt?  [or /dev/rmt/xn for Solaris]
mt rewind
tar xv				# get info file #1
***if you are in Solaris,  just smile****
***if you are in the old SunOS, mt fsf 1 is needed
******to get past the file mark.
tar x [D209 D210 ...] 		# All days [or enumerated days only]	
mt rewind

---------------------------------------------------------

Database tables for this experiment are released in volume SS93_DB

Corrections to database: 
Zero length files.  Delete from db
Adjust file lengths and end times in db.

=================================================================
Unredeemable garbage:

In the following cases,  the dataloggers hiccuped in the middle of a half-hour record
	and created two short records instead of one standard lenth.  Unfortunately, the
	segyheaders show some weirdness,  and it is difficult to fix everything.  On the
	probability that there isn't important data there,  the second short record is omitted
	from the wfdisc. Only Murphy knows why this previously undetected bug hit 3 stations on
	the same day.

HM00,  days 260 to 262 represents some world class screwups by your humble field crew.
For one day,  we had channels 1-3 selected in stream 1 definition,  but the wires were from 4-6.
So,  the fact that the db is missing entries for part of 260 is a wash.
Days 261 and 262 might be ok.

We did get the refraction and CKE streams (2 through 6) ok,  but not here.
