# Image database metadata.  Version of 2007.02.07
#
# Fileds marked with * are mandatory
# 
#
#  DATE_OBS    -- observation date. Calendar date of the experiment nominal
#                 start. Used for file naming.
#
#  DIR_LAYOUT  -- Code of the original directory layout. Used for selecting
#                 files with fits-maps and calibrated+edited visibilities.
#                 If you do not understand what is it, put '??????'
#
# *FIL_CAT     -- Name of the source catalogue. Used for renaming the source
#                 To IAU J2000-name and for putting into fits header comments
#                 precise coordinates and their rates
#
#  RAD_WEI_USE -- Flag whether to use weights stored in the visibility file
#                 for computing scan-averaged flux density. If "F", then
#                 negative or zero weights means that the visibility is 
#                 deselected, but positive weight is replaced with 1.0
#
#  RAD_CUT_ERR -- the cutoff criteria for removing point at radplots and
#                 in the correlated flux density statistics. The point 
#                 with the the amplitude formal error greater than the
#                 product of the visibility amplitude and this factor is 
#                 discarded. The formal error of the amplitude averaged over
#                 frequency and time during the scan is computed on the basis
#                 of the scatter with respect of the mean value.
#
# *PROJ_NAME   -- Project name. Put in the fits header
#
# *SEGMENT     -- Name of the project segment. Put in the header.
#
# *URL_STR     -- URL of the project or n/a
#
# *AUTH_STR    -- First and last name of the person who processed the data
#                 and generated the map.
#
# *N_REF       -- The number of lines with references. Maybe the name of the
#                 publication or name(s) of the person(s) involved in the 
#                 project, or n/a
#
# *REF_STR(x)  -- the x-th line with the references or n/a
#
# *REF_PREP    -- the URL of the preprint or the full-size publication or n/a
#
# *REF_DOI     -- Digital object identified of the main publication related
#                 to the data or n/a
#
# *REF_CDS     -- Reference abbreviating in the CDS format or n/a.
