3. Continuum Observing Programs on the HP1000 and PC

3.1 Test programs

CALT

Essentially a cutdown version of a continuum observing program. Interactively configures and calibrates receivers by firing a noise diode and sampling the output of the selected receiver. Written by MG. Source code hpcontinuum/test/calt.ftn, in nccs/doc/continuum/hpcontinuum/test/calt.ftn.

3.2 Scanning programs

The first drift scan program was written by Don Cameron (sixcm).

DSCAN

Interactive multiwavelength drift scans, written by MG. Used for tests and as a training program for students. Source code hpcontinuum/scan/dscan.all, in nccs/doc/continuum/hpcontinuum/scan/dscan.all.

DSCN9

Automated non-interactive drift scans, derived from DSCAN, written by MG. Source code hpcontinuum/scan/dscn9.ftn, in nccs/doc/continuum/hpcontinuum/scan/dscn9.ftn.

OBCIR

Multiwavelength drift scans through Circinus X-1, written by GN. Source code hpcontinuum/scan/obcir.ftn, in nccs/doc/continuum/hpcontinuum/scan/obcir.ftn.

SIXCM

Obsolete 6cm drift scan program, written by DC, GN. Source code hpcontinuum/scan/sixcm.ftn, in nccs/doc/continuum/hpcontinuum/scan/sixcm.ftn.

THRCM

Obsolete 13cm drift scan program, written by DC, GN. Source code hpcontinuum/scan/thrcm.ftn, in nccs/doc/continuum/hpcontinuum/scan/thrcm.ftn.

3.3 Stepping programs

The stepping programs all derive from a single program originally written by Don Bramwell.

OBCAL

Runs under SCHDL. Steps around a single beam at all frequencies. Step sequence as per TNSTP. Source code hpcontinuum/step/obcal.ftn, in nccs/doc/continuum/hpcontinuum/step/obcal.ftn.

OBPLN

Runs under SCHDL. Observe any planet. Step sequence as per TNFPC. Source code hpcontinuum/step/obpln.ftn, in nccs/doc/continuum/hpcontinuum/step/obpln.ftn. Routines for reading MICA planetary predictions hpcontinuum/step/plnet.sub, in nccs/doc/continuum/hpcontinuum/step/plnet.sub.

OBQCK

Runs under SCHDL(?) Observe any planet in highspeed "interlaced mode" at both 3.5cm and 6cm. Source code hpcontinuum/step/obqck.ftn, in nccs/doc/continuum/hpcontinuum/step/obqck.ftn. Written by JQ. Tracks at (?):

 ZCCAL, ON. 

TNFPC

Source code hpcontinuum/step/tnfpc.ftn, in nccs/doc/continuum/hpcontinuum/step/tnfpc.ftn. For dual beams full pointing is done only in declination. Zero-crossing point provides east-west pointing if no inflection between the beams. Tracks at:

FNNA, HPNA, ONA, HPSA, FNSA, ZC, FNNB, HPNB, ONB, HPSB, FNSB
For single beams there is no east-west pointing check. Tracks at:
FNN, HPN, ON, HPS, FNS

TNFQS

"Quick Step". Source code hpcontinuum/step/tnfqs.ftn, in nccs/doc/continuum/hpcontinuum/step/tnfqs.ftn. For both dual and single beams, does no pointing. Tracks at:

FNNACAL, ONA, FNSA

TNSTP

Source code hpcontinuum/step/tnstp.ftn, in nccs/doc/continuum/hpcontinuum/step/tnstp.ftn. For dual beams, does pointing in both Dec and HA using HP points, with zero-crossing as last point, but otherwise does not use the second beam. Tracks at:

FNNACAL, HPNA, ONA, HPSA, FNSA, FNEA, HPEA, ONA, HPWA, FNWA, ZC
For single beams, does pointing in both Dec and HA using HP points. tracks at:
FNNCAL, HPN, ON, HPS, FNS, FNE, HPE, ON, HPW, FNW

3.4 Mapping Programs

The mapping programs on the HP1000 all derive from SKYMAP, developed over the aeons by Rhodes University (Pete Mountfort, Justin Jonas et al.) for mapping at 13cm wavelength.

SKYMAP

Program for mapping in equatorial coordinates at 13cm, using calls to HP-STEER. Source code hpcontinuum/map/skymap.ftn, in nccs/doc/continuum/hpcontinuum/map/skymap.ftn.

BEAM6

Program for multiwavelength small area mapping in equatorial coordinates, using calls to HP-STEER, derived from SKYMAP by MG. Source code hpcontinuum/map/beam6.ftn, in nccs/doc/continuum/hpcontinuum/map/beam6.ftn.

SUN7

Map the Sun in Ecliptic coordinates using calls to Pascal PC-STEER. Written by JQ? Source code hpcontinuum/map/sun7.ftn, in nccs/doc/continuum/hpcontinuum/map/sun7.ftn. Superceded by MAPR3.

MOON

Map the Moon in apparent Equatorial coordinates using calls to Pascal PC-STEER. Written by JQ? Source code hpcontinuum/map/moon.ftn, in nccs/doc/continuum/hpcontinuum/map/moon.ftn. Superceded by MAPR3.

MAPR3

Map the Sun in Ecliptic coordinates, the Moon in apparent Equatorial coordinates, or other general object in Galactic or 1950, 2000 or mean (current date?) Equatorial coordinates, using calls to Pascal PC-STEER. Written by JQ. Source code hpcontinuum/map/mapr3.ftn, in nccs/doc/continuum/hpcontinuum/map/mapr3.ftn. The parameter file used by MAPR3 was called hpcontinuum/map/mapprm, in nccs/doc/continuum/hpcontinuum/map/mapprm.

The most recent mapping program is a basket-weaving program written by Sarah Buchner under Justin Jonas' tutelage. It is written in Pascal and is described in her MSc thesis (available in the library). Source code should be on NCCS1 or NCCS2 ?
