二. 程序参数

1. 位置信息

# Ray endpoint 1: ph1(latitude, deg N), alng1(longitude, deg N), h1(height, km)
ph1 = 20
alng1 = 30
h1 = 50
# Ray endpoint 2: ph2(latitude, deg N), alng2(longitude, deg N), h2(height, km)
ph2 = 20
alng2 = 30
h2 = 2000

2. 时间信息

# k=0: input of month only
# k=1: input of year and month
# k=2: input of year, month and day of month
# k=3: input of month and UT
# k=4: input of year, month and UT
# k=5: input of year, month, day of month and UT
# k=6: input of month and LT
# k=7: input of year, month and LT
# k=8: input of year, month, day of month and LT
k = 4

# iyr(year), mth(month), nday(day of month), ut(hour with ut/lt)
iyr = 2021
mth = 1
nday = 0
ut = 12

3. 太阳活动信息

# user input R12/F10.7 for this year and month: (y/n)
yn = 'n' # in subroutine dat_t_sa
# sunspot number (S) or 10.7 cm radio flux (F)
fs = 'F'
# R12(sunspot number), flx(radio flux, >=63 units)
R12 = 100
flx = 100

4. 电子密度信息

# List electron density profile along ray (y/n)
yn = 'n'

在线版本与本地版本的结果存在一定差异

What differs is that the online version uses a different modip map (geomagnetic field). ITU-R version of NeQuick uses a modip map that corresponds to values of the same year that ITU-R coefficients.
