- | {{n05l2pt.py}} This file is being used to do the main calibration of my N05L2 EVN test observations for the ionosphere. It was developed before Cormac really began work on developing the ParselTongue EVN pipeline, so you should check out Cormac' | + | {{: |
[[get_small_source_stats_main]] provides a function to get information about an image, similar to the verb IMSTAT in AIPS. It finds the peak and integrated brightness of a source (in Jy/beam and Jy), as well as the RMS level away from the source, ignoring edge pixels in the image. | [[get_small_source_stats_main]] provides a function to get information about an image, similar to the verb IMSTAT in AIPS.

Also of interest might be the function [[self_cal_source]] which provides a very basic self-calibration functionality. It is rather complex, so you will have to look at the code to see what is going on. SCMAP and similar tasks are already available with AIPS, but I have not found them to be very useful, and prefer to keep lots of control over the self-calibration process. | Also of interest might be the function [[self_cal_source]] which provides a very basic self-calibration functionality.

- | The main part of the software in this file is geared toward testing different ionospheric models, and therefore many operations such as phase referencing of sources are repeated over and over. You might have a look at [[process_phase_reference_data]] to see what is going on. This will also need the file {{n05l2pr.py}}. | + | The main part of the software in this file is geared toward testing different ionospheric models, and therefore many operations such as phase referencing of sources are repeated over and over.

- | The other work for the ionosphere involves creating a new AIPS table (AI) and putting ionospheric data into that table, and then moving the information to make a new CL table. A preliminary set of functions to do this can be found in {{albus_iono.py}}. Have a look at the [[apply_AI_table_to_CL_table]] function to see how to read from an old CL table and create a new one. | + | The other work for the ionosphere involves creating a new AIPS table (AI) and putting ionospheric data into that table, and then moving the information to make a new CL table.
