Data model: plateGuideAdjust

General description: This file gives the adjustments to scale, rotation and shift used in deriving the results for a plateGuideOffsets file. These are given as a function of delta-HA relative to the design HA. These files are not expected to be used directly by the guider, but are stored just for the sake of completeness. Note that these adjustments do NOT include the large shift needed to account for the overall diffraction changes; thus, the shift term listed here is tiny.

Naming convention: plateGuideAdjust-PLATEID6-pP-lLAMBDA5.par (where P is the pointing number starting with 1, and LAMBDA is the wavelength that the offsets are optimized for)

Approximate size: 20 kbytes.

File type: Yanny

Written by products: platedesign

Required header keywords: all found in plateHoles files, plus:

• lambda (float32): wavelength optimized for (should be same as LAMBDA in file name), in Angstroms
• pointing (int32): pointing number (1, 2, etc)

Required column names:

• delha (float32): delta-HA relative to design (deg, positive equals West)
• rot (float32): rotation angle (deg)
• xshift (float32): X shift (mm)
• yshift (float32): Y shift (mm)
