SSI Raw Experiment Data Record (REDR) for Phase 2 - USGS PDS ...

Solid State Imaging Raw Experiment Data Record Software Interface Specification

the target center if visible, otherwise the image is scanned at 20 pixel intervals for a point
at highest resolution.
11) The J2000 coordinate system is used for all orientation calculations.
Application program label interface: Label items may be stored, retrieved, or deleted via
subroutines XLADD, XLGET, or XLDEL, respectively. Subroutine VIC1LAB may be used to
retrieve all ground-calibration labels. The subroutine ABLE86 will extract data from either
flight or ground-calibration labels and return the values in an array. Note that programs
intended for multimission support should not call ABLE86 directly, but use GETLABCON.
When an image is map-projected, the following label items relating to image geometry are
updated by MAP3: SUNAZ, SMRAZ, SCAZ, NORAZ, SMRAZ, LAT, LON, HSCL, VSCL.
This is not yet implemented.
