7 A multiplying factor for all the candela values in the file. This makes it
possible to easily scale all the candela values in the file when the
measuring device operates in unusual units—for example, when you
obtain the photometric values from a catalog using a ruler on a
goniometric diagram. Normally the multiplying factor is 1.
8 The number of vertical angles in the photometric web.
9 The number of horizontal angles in the photometric web.
10 1
11 The type of unit used to measure the dimensions of the luminous
opening. Use 1 for feet or 2 for meters.
12 The width, length, and height of the luminous opening. It is normally
given as 0 0 0.
13 1.0 1.0 0.0
14 The set of vertical angles, listed in increasing order. If the distribution
lies completely in the bottom hemisphere, the first and last angles must
be 0° and 90°, respectively. If the distribution lies completely in the top
hemisphere, the first and last angles must be 90° and 180°, respectively.
Otherwise, they must be 0° and 180°, respectively.
15 The set of horizontal angles, listed in increasing order. The first angle
must be 0°. The last angle determines the degree of lateral symmetry
displayed by the intensity distribution. If it is 0°, the distribution is axially
symmetric. If it is 90°, the distribution is symmetric in each quadrant.
If it is 180°, the distribution is symmetric about a vertical plane. If it is
greater than 180° and less than or equal to 360°, the distribution exhibits
no lateral symmetries. All other values are invalid.
16 The set of candela values. First, all the candela values corresponding to
the first horizontal angle are listed, starting with the value corresponding
to the smallest vertical angle and moving up the associated vertical plane.
Then, the candela values corresponding to the vertical plane through
the second horizontal angle are listed, and so on until the last horizontal
angle. Each vertical slice of values must start on a new line. Long lines
may be broken between values as needed by following the instructions
given earlier.
