produces a GridMap from a HifiTimelineProduct.
This task makes the GridMap that defines the regular grid to make a cube for a HifiTimelineProduct.
The images would be produced by performing two dimensional gridding of a number of spectra irregularly distributed over some area of the sky observed in a mapping mode. The spectra are read from a number of HifiSpectrumDatasets within the HifiTimelineProduct.
This task computes a regular grid that covers the region of the sky where the spectra have been observed.
HifiTimelineProduct htp
[INPUT, MANDATORY, default=no default value]
|
|
---|---|
container of the spectra for which a regular grid has to be computed |
Double beam
[INPUT, OPTIONAL, default=no default value]
|
|
---|---|
No default value. Provides the antenna beam width (HPBW), in seconds of arc. |
Double1d smoothFactor
[INPUT, OPTIONAL, default=Double1d(2, 1.0), i.e. autocompute]
|
|
---|---|
provides a smooth factor, increasing (broadening) the area of influence (kernel size) used to compute each pixel. |
String datasetType
[INPUT, OPTIONAL, default="science"]
|
|
---|---|
name of the type of HifiSpectrumDatasets that contain the spectra observed by the instrument when aimed to the source. The spectra used for the gridding are only those from the HifiSpectrumDataset's whose type is equal to the given dataset type and flagged as 'isLine' datasets. |
Boolean ignoreOffs
[INPUT, OPTIONAL, default=true.]
|
|
---|---|
tells whether ignore datasets whose type matches the given datasetType(s) but which are not took from the source (isLine column of the HTP' summary table is false in those datasets) or, on the contrary, grab also them. |
