Description:
This routine calculates the NA/AZ offsets from tangent plane offsets
for SCAN map data.
Invocation
CALL SCULIB_SCAN_APPARENT_TP_2_AZNA(OUT_COORDS, N_POS,
N_BOL, ELEVATION, PAR_ANGLE, BOL_DEC, BOL_RA, STATUS)
Arguments
OUT_COORDS =
_CHAR (Given)
Output coordinate system
N_POS = _INTEGER (Given)
Number of ‘samples’
taken
N_BOL = _INTEGER (Given)
Number of bolometers in the input data
ELEVATION (
N_POS ) = _DOUBLE (Given)
Elevation of each exposure
PAR_ANGLE ( N_POS ) = _DOUBLE
(Given)
Parallactic angle of each exposure
RA_CEN = _DOUBLE (Given)
apparent RA of
output map centre (radians) Only used for JIGGLE data.
DEC_CEN = _DOUBLE (Given)
apparent Dec of output map centre (radians) Only used for JIGGLE data.
BOL_DEC(N_BOL,
N_POS) = _DOUBLE (Returned)
Apparent DEC of bolometers for each measurement
for MJD_STANDARD
BOL_RA(N_BOL, N_POS) = _DOUBLE (Returned)
Apparent
RA of bolometers for each measurement for MJD_STANDARD
STATUS = _INTEGER
(Given & Returned)
Global status
Notes:
This routine does not annul the locator.
Prior
Requirements
The locator to the structure must already be available.
