Hi all,

As for the sun-coefficient simulation part of 5-phase method, the annual sky-matrix is generated as follows:

```
gendaymtx -m 6 -5 0.533 -of assets/NYC.wea > skyVectors/NYCd6.smx
```

where -m 6 means 5185 subdivisions of sky and the term -5 0.533 indicates that the sky-matrix is being generated for the Five-Phase Method. The value of 0.533 corresponds to the size of the solar disc. How to calucate this value 0.533?

So there is a question: when m is other number like 1, and the subdivisions are 145, so how about the corresponding size of solar disc? I guess the value should be larger than 0.533. And what is the relationship between the m and the size of the solar disc?

Any help or advice is appreciated!
