The deconvolve task is the more appropriate version to use for stand-alone image-domain deconvolution, and will not have the bookkeeping overheads currently present in the sdintimaging task's sd-only mode. Please note that the 'sd' option of the sdintimaging task will be removed in a subsequent release. Please refer to the task deconvolve documentation for instructions on how to prepare image and psf cubes for the deconvolve task for all these modes. 2026-02-10 11:38:12 INFO sdintimaging::::casa Initializing SDINT Helper instance with tmp file tag 421509 2026-02-10 11:38:12 INFO sdintimaging::::casa INT cube setup .... 2026-02-10 11:38:12 INFO sdintimaging::::casa Verifying Input Parameters 2026-02-10 11:38:12 INFO SynthesisImagerVi2::selectData MS : papersky_mosaic.ms | [Opened in readonly mode] 2026-02-10 11:38:12 INFO SynthesisImagerVi2::selectData NRows selected : 157950 2026-02-10 11:38:13 INFO SynthesisImagerVi2::defineImage Define image coordinates for [tst.mos_mfs_sdonly.int.cube] : 2026-02-10 11:38:13 INFO SynthesisImagerVi2::defineImage Define image coordinates for [tst.mos_mfs_sdonly.int.cube] : 2026-02-10 11:38:13 INFO MSTransformRegridder::calcChanFreqs phaseCenter='Direction: [0.377371, -0.657097, 0.652545]' Channels equidistant in freq 2026-02-10 11:38:13 INFO MSTransformRegridder::calcChanFreqs+ Central frequency (in output frame) = 1.49983e+09 Hz 2026-02-10 11:38:13 INFO MSTransformRegridder::calcChanFreqs+ Width of central channel (in output frame) = 4.99945e+08 Hz 2026-02-10 11:38:13 INFO MSTransformRegridder::calcChanFreqs+ Number of channels = 3 2026-02-10 11:38:13 INFO MSTransformRegridder::calcChanFreqs+ Total width of SPW (in output frame) = 1.49983e+09 Hz 2026-02-10 11:38:13 INFO MSTransformRegridder::calcChanFreqs+ Lower edge = 7.49917e+08 Hz, upper edge = 2.24975e+09 Hz 2026-02-10 11:38:13 INFO SynthesisImagerVi2::defineImage Impars: start 2026-02-10 11:38:13 INFO SynthesisImagerVi2::defineImage Shape: [1500, 1500, 1, 3] Spectral: [9.99889e+08] at [0] with increment [4.99945e+08] 2026-02-10 11:38:13 INFO SynthesisImagerVi2::defineImage Set Gridding options for [tst.mos_mfs_sdonly.int.cube] with ftmachine : mosaicft 2026-02-10 11:38:13 INFO SynthesisImager::getVPRecord Using default Voltage Patterns from the VPManager 2026-02-10 11:38:13 INFO VPSkyJones::VPSkyJones PB used EVLA 2026-02-10 11:38:13 INFO SynthesisImagerVi2::nSubCubeFitInMemory Required memory: 0.7966 GB.
