NAME
Convolve - convolve an image with a given kernelSYNOPSIS
astconvolve [ OPTION...] ASTRdataDESCRIPTION
Convolve is part of GNU Astronomy Utilities 0.19. Convolve will convolve an input image with a given spatial kernel (image) in the spatial domain (no edge effects) or frequency domain. The latter suffers from edge effects, but can be much faster. For more information, please run any of the following commands. In particular the second contains a very comprehensive explanation of Convolve's invocation: expected input(s), output(s), and a full description of all the options.- All options and their values:
- $ astconvolve -P
- Inputs/Outputs and options:
- $ info astconvolve
- Full section in manual/book:
- $ info Convolve
- Full Gnuastro manual/book:
- $ info gnuastro
- $ info help-gnuastro
- Input:
- -c, --column=STR
- Column name or number if input is a table.
- -h, --hdu=STR/INT
- Extension name or number of input data.
- -H, --minsharpspec=FLT
- Deconvolution: min spectrum of sharp img.
- --kernelcolumn=STR
- Column name or number if kernel is a table.
- -k, --kernel=FITS
- File name of kernel for convolution.
- --nokernelflip
- Do not flip the kernel image.
