string | LinearityType = "LookupTable" |
Correct non-linearity with a persisted lookup table. The lookup table consists of entries such that given "coefficients" c0, c1: for each i,j of image: rowInd = int(c0) colInd = int(c1 + uncorrImage[i,j]) corrImage[i,j] = uncorrImage[i,j] + table[rowInd, colInd] - c0: row index; used to identify which row of the table to use (typically one per amplifier, though one can have multiple amplifiers use the same table) - c1: column index offset; added to the uncorrected image value before truncation; this supports tables that can handle negative image values; also, if the c1 ends with .5 then the nearest index is used instead of truncating to the next smaller index

Correct for non-linearity. Parameters ---------- image : `lsst.afw.image.Image` Image to be corrected kwargs : `dict` Dictionary of parameter keywords: ``"coeffs"`` Columnation vector (`list` or `numpy.array`). ``"table"`` Lookup table data (`numpy.array`). ``"log"`` Logger to handle messages (`logging.Logger`). Returns ------- output : `tuple` [`bool`, `int`] If true, a correction was applied successfully. The integer indicates the number of pixels that were uncorrectable by being out of range. Raises ------ RuntimeError: Raised if the requested row index is out of the table bounds.
