Sample Data Page (Star Removal)
The Sample Data page lists measurements for all marked template and target objects. The data in this table can be used to inspect or compare the objects you have marked. You might then decide to take some action such as deleting one of the template samples.
Sample Data Columns
|
Image |
The image. |
|
Sample |
Specifies the sample type and serial number for each image. Template samples are named "Tmpl" before their serial number and target objects have a minus sign before their serial number. The minus sign indicates that the object was removed from the image. |
|
FWHM |
The Full Width at Half Maximum ("FWHM") for the object, in units of pixels. |
|
BG |
The estimated background value at the position of the object, in units of ADU (also called "Counts", or "DN") |
|
BG Sigma |
The standard deviation of the background around the fit surface. Since the fit rejects interfering stars and other artifacts, this value characterizes the scatter in the "clean" background around the object. |
|
Net Count |
The total signal of the object above background, in units of ADU (also called "Counts", or "DN"). |
