Merge observation datasets into a single DEMS of df/f.

Parameters:

  • cdb (PathLike[str] | str) – Path of CDB (KID correspondence database) file.

  • ddb (PathLike[str] | str) – Path of DDB (DESHIMA database) file.

  • obsinst (PathLike[str] | str) – Path of the observation instruction.

  • readout (PathLike[str] | str) – Path of the reduced readout FITS.

  • antenna (PathLike[str] | str | None) – Path of the antenna log.

  • cabin (PathLike[str] | str | None) – Path of the cabin log.

  • misti (PathLike[str] | str | None) – Path of the MiSTI log.

  • skychop (PathLike[str] | str | None) – Path of the sky chopper log.

  • weather (PathLike[str] | str | None) – Path of the weather log.

  • dt_antenna (int | str) – Time offset of the antenna log with explicit unit such that (dt_antenna = t_antenna - t_readout).

  • dt_cabin (int | str) – Time offset of the cabin log with explicit unit such that (dt_cabin = t_cabin - t_readout).

  • dt_misti (int | str) – Time offset of the MiSTI log with explicit unit such that (dt_misti = t_misti - t_readout).

  • dt_skychop (int | str) – Time offset of the sky chopper log with explicit unit such that (dt_skychop = t_skychop - t_readout). Defaults to 9 ms (for DESHIMA campaign in 2024).

  • dt_weather (int | str) – Time offset of the weather log with explicit unit such that (dt_weather = t_weather - t_readout).

  • include_disabled_mkids (bool) – Whether to include disabled (e.g. fit-failed) MKID responses in the merged DEMS. Note that such data will be all filled with NaN.

  • include_filterless_mkids (bool) – Whether to include wideband and/or no-filter-information MKID responses in the merged DEMS. Note that such data will be all filled with NaN.

Returns:

Merged DEMS of df/f as xarray DataArray.

Return type:

DataArray
