| Parameter | Mand | Type | Default | Constraints |
| set | yes | dataset | | |
Name of the input FITS data set. If datatype=`column', the table name should be added, following the `:', such as, `input1.ds:SRCLIST'.
|
| datatype | no | string | image | image|column |
The datatype of interest in the input FITS file.
|
| column | yes | string | | |
This parameter is read only if datatype=`column'.
This specifies the name of the column of interest.
|
| withregion | no | boolean | no | |
If set, the task reads regionstyle and relevant parameters to determine the region to calculate the statistics. Note the two parameters minareacoords and maxareacoords are completely independent of this switch.
|
| regionstyle | no | string | circle | circle|annulus |
This parameter is read only if withregion=yes.
This specifies the shape of the region. At the moment, only circle and annulus are allowed, and they mean practically identical.
|
| centrecoords | yes | real list | | |
This parameter is read only if withregion=yes.
It is the list of the image pixel coordinates for the (x,y) axes.
|
| radii | yes | real list | | |
This parameter is read only if withregion=yes.
It specifies a radius (or maybe radii in the future) of the region.
|
| radiiinner | no | real list | 0.0 | |
This parameter is read only if withregion=yes.
It specifies a inner radius (or maybe radii in the future) of the annuluar region.
|
| withmincoords | no | boolean | no | |
If set, the task reads minareacoords.
|
| minareacoords | no | real list | | |
This parameter is read if withmincoords=true.
The area where the coordinates are equal to or larger than these will be taken
into account in the calculation of the statistics.
|
| withmaxcoords | no | boolean | no | |
If set, the task reads maxareacoords.
|
| maxareacoords | no | real list | | |
This parameter is read if withmaxcoords=true.
The area where the coordinates are equal to or smaller than these will be taken
into account in the calculation of the statistics.
|
| withvallower | no | boolean | no | |
If set, the task reads vallower.
|
| vallower | no | real | | |
This parameter is read if withvallower=true.
The pixels of which the value is equal to or larger than this value
will be taken into account in the calculation of the statistics.
|
| withvalupper | no | boolean | no | |
If set, the task reads valupper.
|
| valupper | no | real | | |
This parameter is read if withvalupper=true.
The pixels of which the value is equal to or smaller than this value
will be taken into account in the calculation of the statistics.
