Defined in:

Overview

Builds folder paths for bias (zero-exposure) calibration frames.

Bias frames are organized by the following keywords, which allow WBPP to automatically match biases during calibration of darks, flats, and lights:

Bias_ISO_<value>_EXP_<value>_Bin_<value>_CAMERA_<model>_MONTH_<YYYY-MM>

**Keyword meanings:**

  • ISO: Camera ISO setting

  • EXP: Exposure time (typically 0.0s for bias frames)

  • Bin: Binning mode

  • CAMERA: Camera model

  • MONTH: Year-Month in YYYY-MM format (used for seasonal grouping)

Bias frames are primarily used as the baseline calibration for darks, flats, and lights to remove electronic noise. WBPP uses these keywords to match an appropriate master bias based on the ISO, exposure, binning, and season of acquisition.

See README.md for details on the WBPP calibration workflow.
