UMRAO Database Interface


Long term light curves showing two-week averages of the total flux density for selected sources can be viewed using the links to the source name in the table below. These plots show two-week averages of total flux density only (S) or include both total flux density and linear polarization (SPX). Additionally, tabulated daily averages obtained since September 1, 2009 are available for several gamma-ray-flaring sources observed as part of a Fermi project (T); the format for these tabulated linear polarizations is fractional linear polarization and EVPA (in degrees). Tabular LP data is only included when several daily measurements with P>3sigmaP were obtained. Weekly-averaged data are available on request.

The UMRAO total flux density data are currently being edited and prepared for publication in a compendium paper which will be submitted to ApJ Supplement. The linear polarization data will be included in a separate publication. The data on this website are only partially edited and may still contain an occasional bad measurement. These observations are provided as a service to the astronomical community with the specific intent that they be used for calibrating data obtained with other radio instruments, for placing observations obtained with other instruments in context, and for selecting currently active objects or objects with specific variability properties for inclusion in future observing proposals with other instruments, etc. Please note when comparing UMRAO results with VLBI data that our EVPA range is 0-180 degrees and not 0-360 degrees. If any publication makes use of the long term UMRAO data in these specified ways, please add the following acknowledgement: `This research has made use of data from the University of Michigan Radio Astronomy Observatory which has been supported by the University of Michigan and by a series of grants from the National Science Foundation, most recently AST-0607523.' Inclusion of the recent data in tables obtained as part of the Fermi program should include an acknowledgment to NASA Fermi grants NNX09AU16G, NNX10AP16G, and NNX11AO13G. No light curves, or analysis of these data, may be included in papers submitted for publication without the consent of Hugh or Margo Aller.

The description and plots included here were last updated on August 23, 2012. For questions or for additional data, contact Margo Aller (mfa@umich.edu).
