calwebb_guider: Guide Star Processing

Config

calwebb_guider.cfg

Class

GuiderPipeline

The guider pipeline is only for use with data resulting from the FGS guiding functions: Identification (ID), Acquisition (ACQ1 and ACQ2), Track, and Fine Guide. The pipeline applies three detector-level correction and calibration steps to uncalibrated guider data, as listed in the table below.

calwebb_guider

dq_init

guider_cds

flat_field

Arguments

The calwebb_guider pipeline does not have any optional arguments.

Inputs

4D raw data

Data model

GuiderRawModel

File suffix

_uncal

The input to calwebb_guider is a single raw guide-mode data file, which contains the original raw data from all of the detector readouts performed during the guider mode episode. The organization of the 4D data array is analogous to that of 4D raw science data, having dimensions of ncols x nrows x ngroups x nintegrations.

Outputs

3D calibrated data

Data model

GuiderCalModel

File suffix

_cal

The output is a 3D (ncols x nrows x nints) countrate product that has been flat-fielded and has bad pixels flagged. For ID mode data, there is only 1 countrate image produced by the guider_cds step, therefore the length of the 3rd array axis is 1. For all other modes, there will be a stack of multiple countrate images, one per integration. See the guider_cds step information for details on how the countrate images are produced for each mode.
