! ================================================================ ! Preferred Dynamic Constraints. 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 ! r r r r r r r r r r ! Minimum number of stations [10 (6 for 3mm)]: 10 ! May we swap PT for a single VLA antenna? [no] ! Consult http://www.aoc.nrao.edu/~lsjouwer/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]: ! Excluded dates plus reason [none]: ! Preferred interval between segments in days [none]: !
