"""Gendaylit Command.
Gendaylit produces a RADIANCE scene description based on an angular distribution
of the daylight sources (direct+diffuse) for the given atmospheric conditions
(direct and diffuse component of the solar radiation), date and local standard
time. The default output is the radiance of the sun (direct) and the sky (diffuse)
integrated over the visible spectral range (380-780 nm). We have used the
calculation of the sun's position and the ground brightness models which
were programmed in gensky.
Args:
month: An integer representing the number of the month. Count starts from 01.
day: An integer representing the number of the day in a month. Count starts
from 01.
time: A string representing hour and minute in 24 hours format.
Examples of acceptable format are 21.30 and 21:30.
time_zone: A three letter text representing the time zone.
Following are acceptable time zones with their corresponding hour
differences from Greenwhich mean time;
YST +9, PST +8, MST +7, CST +6, EST +5, GMT 0, CET -1, EET -2, AST -3,
GST -4, IST -5.5, JST -9, NZST -12, YDT +8, PDT +7, MDT +6, CDT +5,
EDT +4, BST -1, CEST -2, EEST -3, ADT -4, GDT -5, IDT -6.5, JDT -10,
NZDT -13
solar_time: A boolean to use local solar time. If set to True then the time
is preceded by '+' sign and local solar time is used instead of local
standard time.
options: Command options. It will be set to Radiance default values
if unspecified.
output: File path to the output file (Default: None).
Properties:
* options
* month
* day
* time
* time_zone
* solar_time
* input
