## Quick Start

### Vjj (two-loops planar)

Load all $qggqV$ coefficients and evaluate them (for exmaple at a $\mathbb{F}_p$ phase space point). These are a basis of the vector space of pentagon-function coefficients.

```python
In [1]: from antares_results.Vjj.qggqll.mhv import lTerms
In [2]: from lips import Particles
In [3]: from syngular import Field

# print analytic expressions for the first 5 rational functions in the basis of the vector space of pentagon-function coefficients
In [4]: print(lTerms[:5])
Out [4]: [Terms("""+(+1⟨4|6⟩²)/(⟨1|2⟩⟨2|3⟩⟨3|4⟩⟨5|6⟩)"""), Terms("""+(+1⟨4|6⟩⟨1|4⟩[1|5])/(⟨1|2⟩⟨2|3⟩⟨3|4⟩⟨1|5+6|1])"""), Terms("""+(-1⟨1|6⟩[2|3]⟨4|6⟩)/(⟨1|3⟩⟨2|3⟩⟨5|6⟩⟨1|2+4|3])"""), Terms("""+(+1[2|3]⟨4|6⟩⟨2|6⟩)/(⟨1|2⟩⟨2|3⟩⟨5|6⟩⟨2|3+4|2])"""), Terms("""+(+1⟨3|6⟩[2|3]⟨4|6⟩)/(⟨1|3⟩⟨2|3⟩⟨5|6⟩⟨3|2+4|3])""")]

# generate a random phase space point (in this case over finite fields) and evaluate the basis
In [5]: oPs = Particles(6, field=Field("finite field", 2 ** 31 - 1, 1), seed=0)
In [6]: lTerms(oPs)
Out [4]: [1162389822 % 2147483647, 1610387318 % 2147483647, 173910601 % 2147483647, 1377129258 % 2147483647, 2082634606 % 2147483647, ...]
```

Floating point (real or complex) and $p$-adic phase space points work much in the same way.

### ttH (one-loop)

Load all $qqttH$ coefficients. These are directly coefficients of the respective Feynman integrals (labeld by external legs and internal mass routings).

```python
In [1]: from antares_results.ttH.qqttH.pm import coeffs as qqttH_pm_coeffs
In [2]: qqttH_pm_coeffs.keys()
Out [2]:  dict_keys(['tree', 'bub12x00', 'tri12x3x00m', 'box3x12x4xm00m', 'tri13x24xm0m', 'box3x4x12xm0mm', 'box3x1x24xm00m', 'bub13xm0', 'bub34xmm', 'tri124x3xm0m', 'bub1234xmm', 'tri12x3xmm0', 'bub123xm0', 'box4x2x1xm000', 'tri12x34xmmm', 'bub12xmm'])
In [3]: from antares_results.ttH.momenta import oPsKCheck  # load a phase space point
In [4]: {key: val(oPsKCheck) for key, val in qqttH_pm_coeffs.items()}
Out[4]:
