pilot_fields_info¶

This script allows you to obtain basic information on fields in the VAST Pilot Survey.

The script will print out a table containing the following information for a searched field(s):

EPOCH
FIELD_NAME
SBID
RA_HMS (Beam 0)
DEC_DMS (Beam 0)
DATEOBS
DATEEND

In addition you can request the script return the largest or calculated common psf of the field per epoch, as well as printing all the information of the individual ASKAP beams.

Running the script¶

There are two methods in which to define the fields you wish to query:

Command line: enter your field(s) as so:

pilot_fields_info VAST_0532-50A VAST_1212+00A VAST_2257-06A

Or use an input csv file, which must have the column field_name:

ra,dec,name,sbid,field_name
321.749583333333,-44.2686111111111,Q 2123-4429B,9673,VAST_2112-43A
348.945,-59.0544444444444,ESO 148-IG02,9673,VAST_2256-56A

pilot_fields_info my_fields.csv

If you wish to save the output then using the --save flag will write the results for each field to their own individual file in the current working directory.

See the section below for details on the other options available when running.

Usage¶

Most options should be self explanatory. The lightcurve plots and csv files are saved in the same directory as the input

usage: pilot_fields_info [-h] [--psf] [--largest-psf] [--common-psf] [--all-psf] [--save] [--quiet]
                            [--debug] [--nice NICE]
                            fields [fields ...]

positional arguments:
  fields         Fields to query (or csv file containing fields).

optional arguments:
  -h, --help     show this help message and exit
  --psf          Include the used PSF of the 36 beams that make up the field. Usually set from beam
                 00. (default: False)
  --largest-psf  Include the largest PSF of the 36 beams that make up the field. (default: False)
  --common-psf   Include the common PSF of the 36 beams that make up the field. (default: False)
  --all-psf      Include all the PSF information for the field. (default: False)
  --save         Save the resulting information. Files will be saved to the current working directory
                 in the form of 'VAST_XXXX+/-XXA_field_info.csv'. (default: False)
  --quiet        Turn off non-essential terminal output. (default: False)
  --debug        Turn on debug output. (default: False)
  --nice NICE    Set nice level. (default: 5)
