There is one instance for each circle-year.
.lat, .lon
These two fields are the composite key used to relate a circle-year to a circle.
.year_no
The year number as a string of three digits with
left zero fill, e.g., “008”. See Section 3.3, “Year number”.
.year_key
The year key for this circle-year, left-justified and
blank-filled to length 5. S see the discussion of the
year_key attribute in Section 4.1.7, “Attributes of the efforts table”. Example values (where
_ represents a space):
0001_ 0027_ 0027b NMZU_
.yyyymmdd
Date as a datetime.date object.
.n_obs
Number of observers as an int.
.ph_tot, .ph_foot,
.ph_car, .ph_other,
.h_fd, .h_owl, .pm_tot, .pm_foot, .pm_car, .pm_other, and .m_owl
All these hour- and mile-based quantities use
Python's decimal.Decimal type, with
a precision of one digit after the decimal point.
Note that quantities in this type can be formatted
using a “%f” format,
as in this conversational example.
>>> d1=decimal.Decimal('1.4')
>>> d2=decimal.Decimal('3.47')
>>> d3=d1+d2
>>> d3
Decimal('4.87')
>>> "%6.1f" % d3
' 4.9'
>>> "%6.3f" % d3
' 4.870'
.circle
The Circle instance for to this
circle-year.
.censuses
An iterator that produces all the Census instances for this circle-year.
