| The image dataset to be smoothed. | ||||
| outset | no | dataset | outimage.ds | |
| The resulting smoothed data set. | ||||
| copydss | no | boolean | yes | yes/no |
| Whether to look for a DSS in the input image set and copy it to the smoothed image set. | ||||
| smoothtype | no | string | `adaptive' | simple|adaptive |
| The type of smoothing desired. | ||||
| sigma | no | real | 1.0 pixels | 0.0 |
| If smoothtype='simple' is chosen, the value of the width | ||||
| ngauss | no | integer | 20 | 2 |
| If smoothtype='adaptive' is chosen, the maximum number of gaussian smoothing kernels is specified via this parameter. | ||||
| minsigma | no | real | 0.0 pixels | 0.0 |
| If smoothtype=`adaptive' is chosen, the minimum allowed value of the width | ||||
| maxsigma | no | real | 5.0 pixels | 0.0 |
| If smoothtype='adaptive' is chosen, the maximum allowed value of the width | ||||
| desiredsnr | no | real | 10.0 | 1.0 |
| If smoothtype=`adaptive' is chosen, the maximum desired signal-to-noise ratio of the output image can be specified via this parameter. | ||||
| readtemplateset | no | boolean | no | yes/no |
| Before beginning (adaptive) smoothing, read from the template set specified by templateset. | ||||
| writetemplateset | no | boolean | yes | yes/no |
| After completion of (adaptive) smoothing, write to the template set specified by templateset. | ||||
| templateset | no | dataset | template.ds | none |
| Name of the template image to be read and/or written. | ||||
| withvarianceset | no | boolean | no | yes/no |
| Look for the name of a variance image on the command line. | ||||
| varianceset | no | dataset | none | |
| Name of the variance image. | ||||
| withinmaskset | no | boolean | no | yes/no |
| Look for the name of a weighting mask image on the command line. | ||||
| inmaskset | no | dataset | none | |
| Name of the weighting mask image. | ||||
| withoutmaskset | no | boolean | no | yes/no |
| Look for the name of a clipping mask image on the command line. | ||||
| outmaskset | no | dataset | none | |
| Name of the clipping mask image. | ||||
| writebadmaskset | no | boolean | no | yes/no |
| Write the badmaskset. | ||||
| badmaskset | no | dataset | badpix.ds | none |
| Name of the map of pixels which were unable to be smoothed because the weight was too low. | ||||
| withsrclistset | no | boolean | no | yes/no |
| Look for the name of a source list on the command line. | ||||
| srclistset | no | dataset | none | |
| Name of the source list (the output of either eboxdetect
or emldetect
can be used). | ||||
| expression | no | string | `ID_BAND==0' | none |
| Source selection expression. | ||||
| racol | no | string | RA | none |
