Alter [defaults] as desired. ================================================================ Equipment constraints: Stations. Below each station code, the "o" indicates an [optional] station that is to be used if it is available. Change "o" to "r" if the station is required or change "o" to "n" if the station is not to be used. SC HN NL FD LA PT KP OV BR MK o o o o o o o o o o Minimum number of stations [7]: May we swap PT for a single VLA antenna? [yes] Consult http://www.aoc.nrao.edu/~gtaylor/y1gotcha.html to decide. If you adopt the default, then both PT and VLA1 must be in the stations list in the keyin file. Bands and polarizations. Below each band code, insert "R" if the righthand polarization is to be used, "L" if the lefthand polarization is to be used, "d" if dual polarizations are to be used, or "o" if the band is in your setups but scheduling should not be constrained by its availability. 90cm 50cm 20cm 13cm 6cm 4cm 2cm 1cm 7mm 3mm d Weather constraints: [appropriate for bands marked "L", "R", or "d" above and for at least the minimum number of stations] Date constraints: Preferred date(s), usually a series start [none]: For night-time observations (since this is 90cm), observe April 1, 2005 or later. Excluded dates plus reason [none]: Preferred interval between segments in days [none]: Special conditions (e.g., a series with different spacings in time) [See the comments at the top.]: Schedule for VLBA_NL (Code Nl ) Page 2 Structure and Spectra of High-z Quasar Jets UP: D => Below limits; H => Below horizon mask. blank => Up.
