!   Preferred Dynamic Contraints.  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.

!       Minimum number of stations [9 (6 for 3mm)]: 8
!       May we swap PT for a single VLA antenna? [yes] no
!          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.

! 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]:
!    Special conditions (e.g., a series with different
!       spacings in time) [none]:

! Switching cycle at 6 cm proven to be ok in bm170
! Switching cycle at 1 cm experimental:
!   cycle time is ok for average weather (see VLBA memos #20 and 24)
!   0957+5522 has peaks of 64 mJy/106 mJy at 4.8/15 GHz. Assuming it has
!   100 mJy at 22 GHz, single baseline sensitivity in 53 s (*) is 15.6 mJy, so 
!   fringe-fitting should make a (100/15.6)*sqrt(8) = 18.1 sigma detection
!   if 8 stations are observing -> 1 min cycle-time is ok
!
! (*) 1 min cycle time means that 53 s are spent on-source, use sumitem=dwell to show in summary
