Table of values for codes found within the ulydcode.tab dataset. See Gruen et al. (1995a) for more information. The integer codes do not represent a definite value, but a possible range of values. A value represented within this table is the logarithmic mean of the upper and lower limit of that range. If no value exists for a given integer code, a null value specified by the keyword 'MISSING_CONSTANT' is inserted.

INTEGER CODE -
This is an integer code assigned
to different ranges of physical values for different observables.
ION AMPLITUDE -
The possible range of amplitudes from
the ion collector is divided into logarithmic bins. The ION AMPLITUDE
corresponds to the logarithmic mean of the lower and upper values of
each bin. INTEGER CODE values 0 and 60 are boundaries for the amplitude
measurements. An ION AMPLITUDE less than 9.00E-15 coulomb is assigned
the INTEGER CODE of 0, and an ION AMPLITUDE greater than or equal to
9.00E-09 coulomb is assigned an INTEGER CODE of 60.
ELECTRON AMPLITUDE -
The possible range of amplitudes from
the electron collector is divided into logarithmic bins. The
ELECTRON AMPLITUDE corresponds to the logarithmic mean of the lower
and upper values of each bin. INTEGER CODE values 0 and 60 are
boundaries for the amplitude measurements. An ELECTRON AMPLITUDE greater
than -8.50E-15 coulomb is assigned the INTEGER CODE of 0, and an ELECTRON
AMPLITUDE less than or equal to -1.05E-09 coulomb is assigned an INTEGER
CODE of 60.
CHANNELTRON AMPLITUDE -
The possible range of amplitudes from the
channeltron is divided into logarithmic bins. The CHANNELTRON AMPLITUDE
corresponds to the logarithmic mean of the lower and upper values of each
bin. INTEGER CODE values 0 and 31 are boundaries for the amplitude
measurements. A CHANNELTRON AMPLITUDE greater than -8.80E-14 coulomb is
assigned the INTEGER CODE of 0, an a CHANNELTRON AMPLITUDE less than or
or equal to -1.70E-09 coulomb is assigned an INTEGER CODE of 31.
ENTRANCE GRID AMPLITUDE -
The possible range of amplitudes from
the entrance grid is divided into logarithmic bins. The
ENTRANCE GRID AMPLITUDE corresponds to the logarithmic mean of the lower
and upper values of each bin. INTEGER CODE values 0 and 30 are
boundaries for the negative amplitude measurements. An ENTRANCE GRID
AMPLITUDE greater than -1.50E-14 coulomb and negative are assigned the
INTEGER CODE of 0, and an ENTRANCE GRID AMPLITUDE less than or equal to
-4.00E-10 coulomb is assigned an INTEGER CODE of 30. A positive ENTRANCE
GRID AMPLITUDE has an INTEGER CODE value between 32 and 47. An ENTRANCE
GRID AMPLITUDE less than 1.40E-14 coulomb and positive has an INTEGER CODE
of 32, and an ENTRANCE GRID AMPLITUDE greater than or equal to 9.50E-12
coulomb has an INTEGER CODE of 47
ION RISE TIME -
The possible range of times from the
rise time of the ion collector signal is divided into logarithmic
bins. The ION RISE TIME corresponds to the logarithmic mean of the
lower and upper values of each bin. INTEGER CODE values 0 and 15 are
boundaries for the rise time measurements. An ION RISE TIME less than
10.0 microseconds is assigned the INTEGER CODE of 0, and an ION RISE TIME
greater than 96.5 microseconds is assigned an INTEGER CODE of 15.
ELECTRON RISE TIME -
The possible range of times from the
rise time of the electron collector signal is divided into logarithmic
bins. The ELECTRON RISE TIME corresponds to the logarithmic mean of the
lower and upper values of that bin. INTEGER CODE values 0 and 15 are
boundaries for the rise time measurements. An ELECTRON RISE TIME less
than 10.0 microseconds is assigned the INTEGER CODE of 0, and an ELECTRON
RISE TIME greater than 96.5 microseconds is assigned an INTEGER CODE of
15.
ELECTRON ION TIME -
The possible range of values of the start
time of the electron collector signal minus the start time of the ion
collector signal is divided into logarithmic bins. ELECTRON ION TIME
corresponds to the logarithmic mean of the lower and upper values of that
bin. INTEGER CODE values 0 and 15 are boundaries for the signal time
difference measurements. ELECTRON ION TIME values less than -5.0
microseconds are assigned the INTEGER CODE of 0, and ELECTRON ION TIME
values greater than 45.0 microseconds are assigned an INTEGER CODE of 15.
ENTRANCE GRID RISE TIME -
The possible range of rise times of the
entrance grid signal is divided into logarithmic bins. The ENTRANCE GRID
RISE TIME corresponds to the logarithmic mean of the lower and upper
values of that bin. INTEGER CODE values 0 and 31 are boundaries for the
rise time measurements. An ENTRANCE GRID RISE TIME less than 1.0
1.0 microseconds is assigned an INTEGER CODE of 0, and an ENTRANCE GRID
TIME greater than 426.0 microseconds are assigned an INTEGER CODE of 31.
