# C878 — Transform the complete File46 head field

## Question

Does the integral outer completion imply integral internal heads?

## Inputs

```json
{
  "anchor_BC": 14006
}
```

## Sources

```json
[
  "File46 §6A.5"
]
```

## Results

```json
{
  "head_field": {
    "path": "model/File46_full_head_image.json",
    "sha256": "8cba8fea255e7d925916785e2833f4e080f1d4c067198eace368b3e8951492a2",

  },
  "rows": [
    {
      "head": 14926,
      "radius": 920,
      "E_radius": 1000,
      "image": 15006,
      "integral": true
    },
    {
      "head": 14896,
      "radius": 890,

      "integral": false
    },
    {

      "radius": 460,
      "E_radius": 500,
      "image": 14506,
      "integral": true
    },
    {
      "head": 14436,
      "radius": 430,
      "E_radius": "10750/23",
      "image": "332888/23",
      "integral": false
    },
    {
      "head": 14006,
      "radius": 0,
      "E_radius": 0,
      "image": 14006,
      "integral": true
    }
  ]
}
```

## Finding

The exact whole field exists, but only apparent14926,14466 and anchor14006 map to integer heads at this anchor. The source920→1000 completion does not make the890 and430 radii integral.

## Reassessment

Determine whether any single integer anchor could repair the full field.

## Checks

```json
{
  "whole_field": true,
  "mixed": true,
  "outer": true
}
```
