The *_multiplier fields apply to fluid reserves added by an addon. NTM Space supplies its celestial oil and gas deposits and gives NTM's oil deposits Kerbin's reserve values. Other deposits use the per-deposit fields.
Fields
| Field | Meaning and default | Range |
|---|---|---|
delay | Ticks between extraction attempts; default 25. | [1, \texttt{i32::MAX}] |
drain_chance | Probability that an extraction depletes its deposit; default 0.025. | [0, 1] |
drain_chance_multiplier | Multiplies a fluid reserve's own drain chance; default 0.5. | [0, \texttt{f64::MAX}] |
gas_multiplier | Multiplies the secondary fluid taken from a fluid reserve; default 0.5. The result is truncated to whole mB. | [0, \texttt{f64::MAX}] |
gas_per_deposit_max | Maximum gas extracted per deposit operation, in mB; default 250. | [0, \texttt{i32::MAX}] |
gas_per_deposit_min | Minimum gas extracted per deposit operation, in mB; default 50. | [0, \texttt{i32::MAX}] |
oil_multiplier | Multiplies the primary fluid taken from a fluid reserve; default 1.5. The result is truncated to whole mB. | [0, \texttt{f64::MAX}] |
oil_per_deposit | Oil extracted per deposit operation, in mB; default 750. | [0, \texttt{i32::MAX}] |
power_capacity | Machine HE buffer capacity; default 250000. | [0, \texttt{i32::MAX}] |
power_consumption | Base HE consumption during operation; default 200. | [0, \texttt{i32::MAX}] |
Validation requires 0 \le \mathrm{gas\_per\_deposit\_max} - \mathrm{gas\_per\_deposit\_min} < \texttt{i32::MAX}.
