> Cycle 8 Call for Proposals: LWA Radio Observatory
> 
> We invite applications for observing time with the LWA Radio Observatory.  At this time proposers can request observations with LWA1, LWA-SV, or an interferometry mode between the two.
> 
> LWA1 offers up to three independently-steerable wide-band beams. Each beam supports two independent tunings over the LWA1 frequency range from 10 to 88 MHz with a FWHM ranging from 15 to 2 degrees. Each tuning can cover up to 20 MHz bandwidth. Two all-dipole modes are also available; a transient buffer narrow (TBN), and a transient buffer wide (TBW).
> 
> LWA-SV offers up to two beams with 2 tunings of 20 MHz each. The two tunings are dependent between the beams, and thus need to be at the same frequency. In addition, two all-dipole modes are available; a transient buffer narrow (TBN) and a transient buffer frequency domain (TBF).  At LWA-SV there is also a commensal all-sky broadband imaging system (BIM) that  provides images of the sky over 20 MHz of bandwidth at a 10 s cadence.
> The frequency range of the image data is set by the first beam tuning.
> 
> For the interferometer mode two beams are used at both LWA1 and LWA-SV, one-beam for calibration and the other beam for the target source.  The correlation produces a fan-beam on the sky with a phase center that is affected by the ionosphere.  The bandwidth available is 2 tunings of 20 MHz each.  For details about the observing setup and data reduction see the online tutorial at: http://www.phys.unm.edu/~lwa/singleB_tutorial.pdf <http://www.phys.unm.edu/~lwa/singleB_tutorial.pdf>
> 
> The deadline for application is midnight MST on November 1, 2019 and covers observations expected to occur in the 2020 calendar year.  The complete call for proposals including a cover page can be found at http://lwa.unm.edu <http://lwa.unm.edu/>.  Support for operations and continuing development of the LWA is provided by the National Science Foundation under grant AST-1835400 of the MSIP program, AGS-1708855 and the Air Force Research Laboratory. We invite proposals from all communities wishing to use this instrument.
> 
> More information about the capabilities of the LWA1 can be found on the LWA web pages http://www.phys.unm.edu/~lwa/status.html <http://www.phys.unm.edu/~lwa/status.html>.  An introduction to using the LWA1 is also available at http://www.ece.vt.edu/swe/lwa1/ <http://www.ece.vt.edu/swe/lwa1/>.
