Appendix L
Special Considerations for EVLA P-band Data Processing in

The EVLA has been equipped with new, wide-band receivers in the range 230 MHz to 470 MHz, known as P-band. Most of the data reduction and imaging at this band are similar to those at other bands, so the following will assume some degree of familiarity with the rest of the ookook, particularly Chapter 4. This guide was initially prepared by Minnie Mao from an earlier guide written by Susan Neff. Enough has changed with the P-band system that a thorough revision of the Appendix has been done.

Note that the choice of file names, disk assignments, catalog numbers, and the like depends on your circumstances and will almost certainly not be the same as those shown in the examples below. Note also that experienced (but still reasonable) EVLA users disagree on the details of data reduction. Some compromise in these details has been attempted below.

RFI, especially in spectral-line observations, has tended to accumulate at the phase center for reasons not well understood. It may be best to observe your sources somewhat offset from the phase center.
