Detailed Description

The asapgrid class is defined to convolve data onto regular
spatial grid. Typical usage is as follows:

   # create asapgrid instance with two input data
   g = asapgrid( ['testimage1.asap','testimage2.asap'] )
   # set IFNO if necessary
   g.setIF( 0 )
   # set POLNOs if necessary
   g.setPolList( [0,1] )
   # set SCANNOs if necessary
   g.setScanList( [22,23,24] )
   # define image with full specification
   # you can skip some parameters (see help for defineImage)
   g.defineImage( nx=12, ny=12, cellx='10arcsec', celly='10arcsec',
                  center='J2000 10h10m10s -5d05m05s' )
   # set convolution function
   g.setFunc( func='sf', convsupport=3 )
   # enable min/max clipping
   g.enableClip()
   # or, disable min/max clipping
   #g.disableClip()
   # actual gridding
   g.grid()
   # save result
   g.save( outfile='grid.asap' )
   # plot result
   g.plot( plotchan=1246, plotpol=-1, plotgrid=True, plotobs=True )

Constructor & Destructor Documentation

def asap.asapgrid.asapgrid.__init__	(	self,
		infile
	)

Create asapgrid instance.

infile -- input data as a string or string list if you want
  to grid more than one data at once.

Member Function Documentation

def asap.asapgrid.asapgrid.plot	(	self,
		plotchan = `-1`,
		plotpol = `-1`,
		plotobs = `False`,
		plotgrid = `False`
	)

Plot gridded data.

plotchan -- Which channel you want to plot. Default (-1) is
    to average all the channels.
plotpol -- Which polarization component you want to plot.
   Default (-1) is to average all the polarization
   components.
plotobs -- Also plot observed position if True. Default
   is False. Setting True for large amount of spectra
   might be time consuming.
plotgrid -- Also plot grid center if True. Default is False.
    Setting True for large number of grids might be
    time consuming.

def asap.asapgrid.asapgrid.save	(	self,
		outfile = `''`
	)

Save result. By default, output data name will be constructed
from first element of input data name list (e.g. 'input.asap.grid').

outfile -- output data name.

def asap.asapgrid.asapgrid.setData	(	self,
		infile
	)

Set data to be processed.

infile -- input data as a string or string list if you want
  to grid more than one data at once.
