Preparing Observational Data

Note

This page is a placeholder and will be expanded in a future update.

Exo_Skryer reads observational data via exo_skryer.read_obs.read_obs_data(). The data file is a whitespace-delimited text file whose path is set in the YAML configuration under data.obs.

File Format

Each row represents one spectral bin. Columns are:

Column	Name	Description
1	wavelength	Central wavelength of the bin [micron]
2	delta_wavelength	Half-width of the wavelength bin [micron]
3	y	Observed quantity (e.g. \((R_p/R_s)^2\) for transmission, \(F_p/F_s\) for emission)
4	dy	Symmetric uncertainty on y (1-sigma). If a 5th numeric column is present it is treated as the negative error bar, and the larger of the two is used.
5 (optional)	response_mode	Instrument response function type for the bin (default: boxcar)
6 (optional)	offset_group	Label grouping bins that share an instrument-offset parameter (e.g. MIRI)

Lines beginning with # are treated as comments.

Example

A minimal four-column file:

# wavelength  dwl       depth      uncertainty
1.0           0.01      0.0207     0.00008
1.1           0.01      0.0205     0.00007

A six-column file with response mode and offset groups:

# wl    dwl     depth     dy       response  offset_group
5.064   0.075   0.020065  0.000084 boxcar    MIRI
5.214   0.075   0.020083  0.000091 boxcar    MIRI
