Basic Observing Commands

High-level commands to the antennas, receivers, and correlators are written in python. To execute these commands, you must open a python environment, called a subarray controller (or SAC). The "science1" SAC typically controls the 10-meter and 6-meter antennas and the Spectral Line (SL) correlator. To open the "science1" SAC, type:


The prompt will change to Sci#1[1]:

To get information about a source

To track a source

To tune the receivers

To configure the correlator

To integrate on a source

Basic Data Reduction Commands

  1. Gathering information about your data set.
  2. Baseline calibration.
  3. Linelength calibration.
  4. Displaying your data.
  5. Flagging bad data.
  6. Passband calibration.
  7. Flux calibration.
  8. Gain calibration.
  9. Inverse Fourier Transform.
  10. Deconvolve
