! Schedule for BS151, epoch1, based on egvlba.key. ! ! ================================================================ ! Preferred Dynamic Constraints.

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 !
