Keeping logs
	We decided to keep logs for all noteworthy activities that we might
	forget later. These are plain text files with a name resembling relevant
	image names.
	Althogh there is no utility to organize and access these logfiles, they
	are kept on $DEEPHOME/logbooks/transfer/*.transferlog
		    $DEEPHOME/logbooks/cleaning/*.cleanlog
		    $DEEPHOME/logbooks/reducing/*.reducelog
		    $DEEPHOME/logbooks/tape/tape##.*

	If new subdirectory is needed feel free to create one.

	In these files mention date of entry, relevant image names, etc.

	For example, a transfer log might look like this; 
	
	dec2994sso.transferlog :
	Jan 24, 1995
	2 AGN2 followup images in R from sso called sn001.fits and sn002.fits
	Date of Observation : dec 28 or 29, 1994
	copied in $dsk5/sso/mike

	Our tape backup convention is all our tapes are to be assigned a unique
	(chronological) number and the content of each tape to be kept as
	$DEEPHOME/logbooks/tape/tape99_jan95intraw.tarlog (if tape99 is tar tape
	of jan95int raw images). This numbering system also apply for all the 
	original tapes from the telescope.


Trouble database
	Any comment about problem in using a particual image should be kept.
	Again, there is no utility for these but we are keeping plain text files
	in $DEEPHOME/database/troubles/*.trouble
	These are one per image thing so that later we may hook up with our
	standard routine like readimage.pro to show these text as warning.

	For example, if jan1295int12ebs.fts has SN candidate but cosmic ray are
	in the near by pixel causing some trouble, make a file
	$DEEPHOME/database/troubles/jan1295int12ebs.trouble
	and type in something like ;
		Cosmic ray at (245,399) too close to our candidate at (243,400)

	If a problem is fixed or somehow no longer relevant, move *.trouble file
	to $DEEPHOME/database/troubles/DONE subdirctory instead of deleting it.


Document files for images
	If there is a peculiar feature of an image useful to remember, it should
	be kept again as simple text file in $DEEPHOME/database/imagedoc/*.doc.
		(Ex. $DEEPHOME/database/imagedoc/jan1295int12ebs.doc)
	The difference of these files and above trouble database files is that
	trouble files are to discourage use of those images while images with
	doc files only are all right to be used.
