NAME

writems - Create one or more MeasurementSets

SYNOPSIS

writems parm= value ...

Parameters

	nms		Number of MeasurementSets to create (0 means 1 MS without suffix; default, >0 also creates MultiMS)
	msname		Name of the output MeasurementSet (suffix _p<i> is added if nms>0)
	ra		One or more J2000 Right Ascensions (as hh:mm:ss.sss); defines the fields
	dec		One or more J2000 Declinations (as dd.mm.ss.sss); defines the fields
	anttab		Name of the ANTENNA table giving the antenna parameters to use (zero/empty values if not given)

startfreq

Start frequency (Hz) per spw (1 value counts on for other spws; default: 1e9)

chanwidth

Channel frequency width (Hz) per spw (1 value applies to all spws; default: 1e6)

starttime

Start time (e.g., 23Mar2016/12:00:00)

timestep

Time interval (sec; default: 1)

	ntime		Number of time steps (default: 1) ntimefield Number of time steps per field (0=all fields for all times; default)
	nspw		Number of spectral windows (default: 1)
	npol		Number of polarizations per spectral window; 1 value applies to all spws (default: 4)
	nchan		Number of channels per spectral window; 1 value applies to all spws (default: 256)

nflagbits

int Write multiple flag bits (0, 8, 16 or 32) mapped to FLAG (default: 0)

flagcolumn

Name of the FlagBits column if nflagbits>0 (default: "FLAG_BITS")

tilesize

	mfsize		MultiFile/HDF5 block size (KBytes); default is tilesize
	ashdf5		bool Write the data in HDF5 format (default: false)
