simms

Creates empty measurement sets using the the CASA simulate tool.

Requires

Install

Github

$ git clone https://github.com/radio-astro/simms
$ cd simms
$ python setup.py install

Pip

pip install simms

Examples

On the command line

To get farmiliar with options run: simms --help ;)

The antenna positions can be specified as a CASA Table or an ASCII file. Bellow is an example of you can an empty MS using both formats:

NOTE: Some antenna tables are provided in Simms/observatories. Run the examples below in the simms directory or change the paths of the antenna files accordingly in the lines bellow.

CASA Table KAT7_ANTENNAS

simms -T kat-7 -t casa -l test_casa -dec -30d0m0s -ra 0h0m0s -st 1 -dt 60 -f0 1.4GHz -nc 4 -df 10MHz Simms/observatories/KAT7_ANTENNAS

ASCII vlac.enu.itrf

simms -T vla -t ascii -cs itrf -l test_ascii -dec 30d0m0s -ra 0h0m0s -st 1 -dt 60 -f0 1.4GHz -nc 4 -df 10MHz Simms/observatories/vlac.itrf.txt

In both cases, we create an empty MS (VLA-A and KAT-7) at 1400MHz with 4 10MHz channels, the observtion is 1hr and has a 60s integrations time.

In Python

from simms import simms

simms.create_empty_ms(msname="Name_of_ms.MS", tel="kat-7", synthesis=1, pos_type='casa', pos="kat-7_antenna_table")
