This is the Australia Telescope Compact Array (ATCA) sensitivity calculator, specifically built to give maximum assistance to users who may not be familiar with the capabilities of the telescope. It aims to guide users through the process of planning an optimal observation strategy, calculate the resulting expected sensitivity and present it in a friendly way.
The calculator that this page uses is identical to the traditional calculator page found here, so users who do not need the extra assistance may continue to use it.
This calculator should be treated as a questionaire. Each panel will ask a series of questions, and when enough valid information is entered, the next panel(s) will open. The panels can be manually opened or closed by clicking on the blue bars. The blue bars also show a summary of the settings made in each panel.
When enough valid information is given by the user, a "Calculate Sensitivity" button will appear in the "Calculation and Results" bar. Clicking this button will close all the panels and present the results.
Questions, comments and issues should be addressed to Jamie (dot) Stevens (at) csiro (dot) au.
- For continuum observations, it is best to select the highest frequency resolution possible, which for CABB is 1 MHz.
- For spectral-line observations, you will generally want to use the correlator mode that will give you the optimum spectral coverage.
- The calculator allows both available and planned CABB modes to be selected: please check the CABB webpage for the modes that have been implemented.
