importmiriad – Convert a Miriad visibility file into a CASA MeasurementSet – import/export task

Description

Convert a Miriad visibility file into a CASA MeasurementSet with optional selection of spectral windows and weighting scheme

Title
Parameter	Default	Description
mirfile	`''`	Name of input Miriad visibility file
vis	`''`	Name of output MeasurementSet
tsys	`False`	Use the Tsys to set the visibility weights
spw	`numpy.array( [ ] )`	Select spectral window/channels
vel	`''`	Select velocity reference (TOPO,LSRK,LSRD)
linecal	`False`	(CARMA) Apply line calibration
wide	`numpy.array( [ ] )`	(CARMA) Select wide window averages
debug	`int(0)`	Display increasingly verbose debug messages

''

Name of input Miriad visibility file: Default: none

Example: mirfile=’mydata.uv’

''

False

Use the Tsys to set the visibility weights: Default: False Options: False|True

numpy.array( [ ] )

Select spectral window/channels: Default: ‘’ (all spectral windows and channels)

Examples: spw=’0~2,4’; spectral windows 0,1,2,4 (all channels) spw=’<2’; spectral windows less than 2 (i.e. 0,1) spw=’0:5~61’; spw 0, channels 5 to 61 spw=’0,10,3:3~45’; spw 0,10 all channels, spw 3 - chans 3 to 45. spw=’0~2:2~6’; spw 0,1,2 with channels 2 through 6 in each. spw = ‘*:3~64’ channels 3 through 64 for all sp id’s spw = ‘ :3~64’ will NOT work.

''

Select velocity reference: Default: telescope dependent, ATCA -> TOPO, CARMA -> LSRK Options: TOPO|LSRK|LSRD

Example: vel=’LSRK’

False

(CARMA) Apply line calibration

Default: False Options: False|True

Only useful for CARMA data

numpy.array( [ ] )

(CARMA) Select wide window averages

Select which of the wide-band channels should be loaded Only useful for CARMA data
