NRAO Home > CASA > CASA Toolkit Reference Manual

2.4.1 Set various processing options

Description

For most of these, set the options for predict details. See also imager help for more details.

To simulate single dish data, use gridft=SD and gridfunction=PB.

Arguments


Inputs
ftmachine	Fourier transform machine. Possibilities are ’ft’, ’sd’
	allowed:	string
	Default:	ft ’ft’
cache	Size of gridding cache in complex pixels
	allowed:	int
	Default:	0
tile	Size of a gridding tile in pixels (in 1 dimension)
	allowed:	int
	Default:	16
gridfunction	Gridding function. String: ’SF’—’BOX’—’PB’
	allowed:	string
	Default:	SF ’SF’
location	Location used in phase rotations. Position Measure of Coordinates of array location. E.g me.position(’ITRF’, ’30.5deg’, ’-20.2deg’, ’6000km’) or me.observatory(’ALMA’)
	allowed:	any
	Default:	variant ALMA position measure
padding	Padding factor in image plane (>=1.0)
	allowed:	double
	Default:	1.3
facets	Number of facets
	allowed:	int
	Default:	1
maxdata	Maximum data to write to a single TSM file (MB)
	allowed:	double
	Default:	2000.0
wprojplanes	Number of projection planes when using wproject as the ft-machine
	allowed:	int
	Default:	1

Returns
bool

Example

sm.setoptions(cache=10000000, tile=32, gridfunction=’BOX’, me.location(’vla’))
