As a part of our exercise we need to determine the lattice parameter of the given xrd peaks (http://bama.ua.edu/~mweaver/courses/MTE481/Lab2_PP.pdf . the last page of the link), here's the peak data:

2theta

23.73

39.23

46.36

56.69

62.31

71.1

76.15

84.35

89.2

97.29

102.21

110.83

115.9

luckily its a tetragonal system, i tried to determine, the lattice parameter, and i got a=b=

2.295, and c =3.7469, but i doubt that's correct because when i tried to simulate it, there are extra peaks. so guys please help me what to do thanks.
