Change Point Data
The Change Point Data dialog is used to view
and modify the reference values used in computing the plate
solution for the Astrometric Calibration tool. Here you can modify
the Right Ascension and Declination of the point as well the (X,Y)
position and weight of the point. You can also delete the point
from the image.
|
Right Ascension
|
The currently used Right Ascension of the
reference point.
|
|
Declination
|
The currently used Right Ascension of the
reference point.
|
|
Residual (RA)
|
The residual difference between the entered value
of Right Ascension and its value predicted by the plate solution.
This is listed in units of arcseconds.
|
|
Residual (Dec)
|
The residual difference between the entered value
of Declination and its value predicted by the plate solution. This
is listed in units of arcseconds.
|
|
Position (X)
|
The current X position of the point.
|
|
Position (Y)
|
The current Y position of the point.
|
|
Status
|
Specifies whether the point is used in computing
the plate solution.
|
|
Weight
|
Specifies the weight of the point used in
computing the plate solution. All points have a weight of 1.0
unless you set it otherwise.
|
|
[Accept]
|
Accepts your changes to the point data.
|
|
[Delete]
|
Deletes the point. The point cannot be recovered
without marking it again.
|
|
[Cancel]
|
Closes the dialog without making changes.
|
The format for Right
Ascension and Declination is
quite relaxed in terms of how the parts are entered and separated.
See the section "Specifying Right Ascension
and Declination" under the
Enter Coordinates topic.
