calwebb_guider: Guide Star Processing¶
- Class
- Alias
calwebb_guider
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.

Arguments¶
The calwebb_guider pipeline does not have any optional arguments.
Inputs¶
4D raw data¶
- Data model
- 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
- 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.
