! Instructions to control reference pointing. ! This file is maintained in $SCHED/catalogs/Master_NRAO/peak.cmd. ! The versions in $SCHED/catalogs/ are produced by Update which ! alters the setup files for each case. ! This file provides information that allows SCHED to create reference ! pointing observations with minimal user input, either in response ! to the POINT command or when using AUTOPEAK. From this, Update in ! the catalogs area will create 3 files, one each for use with Mark5a ! recording, one for the RDBE_PFB and one for the RDBE_DDC. They only ! differ in the specified setup file. ! Not that when POINT or AUTOPEAK are used in RDBE based observations, ! the CRD parameters such as CRDDOP, CRDBW etc are used so that the ! legacy BBCs, whose power data are used for pointing, can be set ! independently of the RDBE. This is required for the RDBE_PFB because ! it cannot use the narrow bandwidths needed for pointing on masers. ! SOURCE CATALOG: ! 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 ! LINE REST FREQUENCIES ! 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. This is being done 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.) ! The first two frequencies are the actual line frequency. lineinit / lineset='PSiO431' restfreq=43122.027, 43122.027, 43222.027, 43222.027 / lineset='PSiO862' restfreq=86243.4, 86243.4, 86443.4, 86443.4 / lineset ='PH2O' restfreq=22235.08, 22235.08, 22285.08, 22285.08 / endlines / ! CONTROL PARAMETERS ! The first three parameters are for automatic insertion of peaking ! scans only and apply to all 3mm groups. minfreq = 60000.0 ! Don't bother for lower frequencies (MHz) dwell = 1:00 ! Duration of peak scan. minel = 10.00 ! Minimum elevation for pointing. ! These also apply to scans for which conversion to pointing is ! requested with POINT. The setup will be modified by Update ! for the appropriate file for each varient of peak.cmd in the ! base catalogs directory. The file choices that replace "pt7mm.set" are: ! pt7mm.set - for non-rdbe observing. "peak.cmd" ! ptd7mm.set - for observing with the RDBE_DDC "peak_RDBE_DDC.cmd" ! ptr7mm.set - for observing with the RDBE_PFB "peak_RDBE_PFB.cmd" ! For line pointing replace "pt7mm.set" with: ! pt7mm.set - for non-rdbe observing. "peak.cmd" ! ptdl7mm.set - for the RDBE_DDC "peak_RDBE_DDC.cmd" ! ptr7mm.set - for the RDBE_PFB "peak_RDBE_PFB.cmd" ! These are the same as the continuum for the old systems and for the ! RDBE. setup = $SCHED/setups/pt7mm.set setupl = $SCHED/setups/pt7mm.set linename = 'PSiO431' ! SOURCES CHOICES ! The VLBA 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. !!

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).

GROUP 1: Eastern VLBA antennas at 3mm. Station names ! or codes can be specified. These apply to inserted scans ! for group 1 or for any scans for which POINT=1 or POINT=0 ! was specified. stations = vlba_sc, vlba_hn, vlba_nl, vlba_fd, vlba_la, vlba_pt, vlba_kp / ! GROUP 2: Western VLBA stations. ! Use most of the same parameters as GROUP 1. stations = vlba_ov, vlba_br, vlba_mk /
