# `Sidereon.SourceLocalization.Crlb`
[🔗](https://github.com/neilberkman/sidereon-ex/blob/main/lib/sidereon/source_localization.ex#L241)

Timing CRLB and DOP for a proposed source and sensor geometry.

DOP values multiply timing sigma in seconds to produce metres for position
terms. Covariance is scaled by the requested timing sigma.

# `dop`

```elixir
@type dop() :: %{
  gdop: float(),
  pdop: float(),
  hdop: float(),
  vdop: float(),
  tdop: float()
}
```

# `t`

```elixir
@type t() :: %Sidereon.SourceLocalization.Crlb{
  covariance: Sidereon.SourceLocalization.Covariance.t(),
  dop: dop()
}
```
