AVN Observation Support Tool
Version 0.001 BETA
Array Setup:
Instrument:
AVN
EVN
AVN+EVN
Select the desired telescope.
Sky Setup:
Source model:
OST Library: Central point source
OST Library: Protostellar Cluster
OST Library: Radio Jet
Choose a
library
source model or supply your own.
Declination:
Ensure correct formatting of this string (+/-00d00m00.0s).
Image peak / point flux in
Jy
mJy
uJy
Rescale the image data with respect to new peak value.
Set to 0.0 for no rescaling of source model.
Observation Setup:
Central frequency in GHz:
The value entered must be within an AVN/EVN band.
Bandwidth in
GHz
MHz
kHz
:
Select the total bandwidth for observations.
Enter small values for single channels and large values for continuum observing.
Pointing strategy:
Single
Selecting single will apply primary beam attenuation.
Start hour angle:
Deviation of start of observation from transit.
Phase Cycle:
seconds
The length of time between cutting to a phase calibrator.
Limited to either 0s or between 300s and 600s.
On Phase Cal. time:
seconds
The length of time spent observing phase calibrator (including slewing time).
Currently limited to either 0s or between 30s and 120s.
On-source time in
seconds
minutes
hours
:
Per pointing for mosaics.
Number of visits:
How many times the observation is repeated.
Number of polarizations:
1
2
This affects the noise in the final map. Ignored in continuum mode if "Use full Stokes parameters" is set to yes.
Atmospheric Corruption:
Atmospheric conditions:
6GHz Weather
Determines level of noise due to water vapour.
Imaging Product:
Imaging weights:
Uniform
Natural
Briggs
This allows a resolution / sensitivity trade-off.
Perform deconvolution?:
No (Return dirty image)
Yes
Apply the CLEAN algorithm to deconvolve the image.
Output image format:
FITS
CASA
CASA format images are returned as a tar file
