Guide Star and Guide Window Information
Outline
Schema Definitions ¶
This type is an object with the following properties:
guide_window_id
asdf://stsci.edu/datamodels/roman/schemas/meta/guide_window_id-1.0.0 Required guide_mode
object Required This node must validate against all of the following:
window_xstart
integer Required Guide Window X Start Position (pixels)
Minimum X position in pixels in the science coordinate frame of all tracking guide windows in this exposure.
window_ystart
integer Required Guide Window Y Start Position (pixels)
Minimum Y position in pixels in the science coordinate frame of all tracking guide windows in this exposure.
window_xstop
integer Required Guide Window X Stop Position (pixels)
Maximum X position in pixels in the science coordinate frame of all tracking guide windows in this exposure.
window_ystop
integer Required Guide Window Y Start Position (pixels)
Maximum Y position in pixels in the science coordinate frame of all tracking guide windows in this exposure.
guide_star_id
string Required Guide Star Identifier
Identification of the guide star from the Guide Star Catalog (GSC). This is based on planned information from the Roman Planning and Scheduling Subsystem.
Maximum length: 20
epoch
string Required Guide Star Coordinates Epoch
Epoch of the celestial coordinates of the guide star from the Guide Star Catalog (GSC).
Maximum length: 10
jitter_major
number Major Axis Jitter (milliarcseconds)
Estimate of the guidestar jitter kernel width (in milliarcseconds) along the major axis of the jitter kernel. When no guidestar was observed with this detector, a default value will be used.
jitter_minor
number Minor Axis Jitter (milliarcseconds)
Estimate of the guidestar jitter kernel width (in milliarcseconds) along the minor axis of the jitter kernel. When no guidestar was observed with this detector, a default value will be used.
jitter_position_angle
number Jitter Position Angle (deg)
Position angle (in degrees) of the jitter kernel in the science coordinate system. The position angle is the angle of the major axis relative to the +Y axis, with PA increasing as the major axis moves toward the +X axis. When no guidestar was observed with this detector, a default value will be used.
