EVLA Data Reduction Workshop Program

by Stephan Witz last modified Feb 21, 2012 by Gustaaf Van Moorsel

Introduction

The EVLA data reduction workshop will cover all aspects of EVLA observing from observing preparation through data reduction This workshop assumes knowledge of the principles of interferometry and familiarity with either CASA or AIPS at a functional level.

14 September (Wednesday):

0800-0815 Coffee

0815-0830 Introduction [van Moorsel]

0830 - 0900 EVLA OSRO/RSRO Capabilities & Operations [McMullin]

Discussion of the current advertised capabilities for the upcoming D configuration; this will cover details of the hardware and software (e.g., correlator system to understand band edges and corresponding noise consequences, data rate realities, and averaging options). This will also cover the current restrictions (dummy scans, slew rates, time on source, etc) and scheduling realities (30 minute granularity, the dynamic scheduling system algorithms and operations).

0900 - 1000 Observing Preparation Guide [Sjouwerman]

Discussion/walk-through of the observing preparation stage: building your instrument configuration, building your source catalog, developing your observing sequence.

1000-1045 Data Reduction Techniques [Momjian]

Sketch general data reduction process, review additional low and high frequency concerns and complications. Focus on getting through narrow-field imaging. Cover current expectations for noise/dynamic range (and when they break down).

1045-1100 Break

1100-1200 Data Reduction Techniques [Momjian] - continued

1200-1330 Lunch

1330-1400 Introduction to CASA [Ott]

Review of task interface, parameter expansion, saving and restoring, in-line help; discussion of data structures, data selection, visualization, customization of the CASA environment.

1400-1700 Hands-on session with EVLA staff

Choose initial data set to work through; load the data and review the observations.

15 September (Thursday)

0800-0815 Group meeting to discuss any general issues/logistics/etc.

0815-1200 Hands-on session with EVLA staff
