!  Instructions to control reference pointing.

!  Specify the source catalog file with pointing sources.  These 
!  will be added to the normal source list so the names should be 
!  distinct from sources in the main source list (often sources.vlba).  
!  Note that some sources in the main list can also be used for pointing.

 srcfile = $SCHED/catalogs/sources.pointing ! Reference pointing sources

! Add the rest frequencies to the list of lines.
! This can also be done in the main schedule inputs.
! For here, use special names that won't conflict with what users
! use in the main program.  I am doing this because there are 4
! rest frequencies given, two of which are off the line for use
! with the pointing setup file, which has 4 channels and allows
! on/off line difference power pointing (although that is not yet
! available for reference pointing, it is used for pointing tests.)

!  There can be up to 5 groups of stations that can have separate
!  pointing scans handled automatically (you can do anything you
!  want using full scan specifications.

!  The first group is for Eastern VLBA antennas at 3mm.  Station names 
!  or codes can be specified.

!  The first three parameters are for automatic insertion of peaking 
!  scans only and apply to all 3mm groups.  The other two also apply
!  to scans for which conversion to pointing is requested with POINT.

minfreq = 60000.0     !  Don't bother for lower frequencies (MHz)
dwell = 2:00          !  Duration of peak scan.
minel = 10.00         !  Minimum elevation for pointing.
setup = $SCHED/setups/pt7mm.set     !  Setup to use for peakup
linename = 'PSiO431'

!  The pointing for 3mm projects will be done at 7mm.  Essentially all
!  useful sources are variable, so the best sources can vary with time.
!  Keeping only the best sources should be fairly reliable.  The other
!  sources here are shown in case it is important to find something
!  closer to the target.  The scheduler will have to add the desired
!  source(s) to the uncommented list and will have to make the decision
!  on whether the source is expected to be usable.

!!! STRONG sources, pretty much guaranteed.  Sources starting with P-
!!! are SiO masers.  The others are continuum sources.
