! RECORD INFORMATION
!
!------------------------------------------------------------------------------
DESCRIPTION "This relation is used to specify the position and
orientation requirements of an alignment. It is
accessed to specify slew commands in the SMS and for
position data sent to GSSS. If the QALIGNMENT record
(QALIGNMENT.scan_type) specifies a spatial scan, both
the initial and final position of the scans are
specified in separate QAPOSITION records. There must
be at least one (when QAPOSITION.initial_pos='B') and
not more than two (when QAPOSITION.initial_pos='I' and
'F') qaposition records for every QALIGNMENT record.
The PMDB/UPDATE/TYPE=obset command calculates various
fields in QAPOSITION, such as CALC_RA, CALC_DC,
CALC_ALGN_TY and CALC_ORI_TY. TRANS supplies the
value of ALIGN_TYPE and ORIENT_TYPE. When ALIGN_TYPE
or ORIE NT_TYPE is 'NL' or 'OF', the calculated values
for CALC_ALGN_TY, CALC_ORI_TY, and other pointing or
orientation fields are determined by PMDB/UPDATE based
on the previous alignment in the obset.
The SPSS code modules QUATAP.FOR and QUAORN.FOR are
called by PMDB/UPDATE, at which time various flags
contained in QAPOSITION are interpreted for the proper
calculation of an alignment's position and
orientation.
GSSS/REQUEST extracts alignment positional data when
constructing the guide star request. GSSS/CENTER
extracts the target and aperture positions.
GSSS/REPORT compares the qaposition angle ranges with
the angle ranges for each guide star pair, marking
a pair unusable if the ranges do not intersect.
The POSANGLE command, which generates a position angle
display, selects the target and aperture positions.
The LOS command (Line-Of-Sight) extracts RA and Dec,
V3 angles, and V2V3 coordinates from qaposition
when no calendar is supplied.
QAC (Qaposition Aperture Correction) updates aperture
reference angle and position fields.
CANDLIST/ADDSUS, CANDLIST/DELSU, CANDLIST/UPDATE,
CCLIST/CREATE, SGS, FOV, NOM_POS and PLANNINGWINDOWS
select alignment positional data.
SMSG/SCHEDULE selects alignment positional data when
generating OSS/PODPS observation records.
SMSG/GENERATE extracts the target id for the
instruction expander."
