## BuildConfig


Options controlling how a UVIS observation is turned into a FITS product.


Usage

``` python
BuildConfig(
    calibration="pyuvis",
    background=Background(),
    write_pds4_label=True,
    fits_version=1.0
)
```


## Attributes


`calibration: CalibrationSource`  
Where the calibrated cube + `CAL_FACTOR` come from:

- `"pyuvis"` (default) -- derive the cal factor from the archived PDS product via `pyuvis` (counts x PDS cal matrix -\> kR). Thin glue, modern path; not wired yet (blocked on real-data ingest).
- `"stored"` -- recalibration: reuse the `CAL_FACTOR` read back from an existing FITS verbatim and only re-apply the background offset. The working path for `~cubegenpy.sources.FitsReadbackSource`.
- `"regenerate"` -- reserved seam for the ported IDL `Get_UVIS_calibration` ("Ultimate" Greg Holsclaw time-varying cal) / `~cubegenpy.calibrate.SpicaCalModel`. Raises until implemented.
- `"none"` -- debug passthrough: fill the primary HDU with counts/sec (unit cal factor); the real `CAL_FACTOR` HDU is still written.

`background: Background`  
How much background to subtract before calibration, as a `~cubegenpy.calibrate.Background` value (not a bool, so it can carry the RTG dark rate or a spectral-average band). Defaults to `mode="none"`.

`write_pds4_label: bool`  
Emit the sibling draft PDS4 XML label.

`fits_version: float`  
Value written to the primary-header `VERSION` keyword.
