!   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
!           o   o   o   o   o   o   o   o   o   o
!       Minimum number of stations [9 (6 for 3mm)]: 8
!       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: none
!    [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]: none
!    Excluded dates plus reason [none]: none
!    Preferred interval between segments in days [none]: none
!    Special conditions (e.g., a series with different
!       spacings in time) [none]: none

! ========================  The Scans  =====================
! ==========================================================

! Strategy:
! Do 2 non-phase cal runs first, then a phase cal run, then 2 non-phase
! cal runs --- other calibrators distributed appropriately 
!

! The Scans:
! Do two non-phase cal rounds first, because MK is not up, and don't want 
! to do phase cal without all stations.
