This command can be used
to fit and remove the sky signal from a SCUBA-2 time series file.
BBM = NDF
(Read)
Group of files to be used as bad bolometer masks. Each data file specified with the
IN parameter will be masked. The corresponding previous mask for a subarray will be
used. If there is no previous mask the closest following will be used. It is not an error for
no mask to match. A NULL parameter indicates no mask files to be supplied. [!]
FIT =
_CHAR (Read)
Type of fit to be carried out for the PLANE sky removal method. Choices are
Mean, Slope (to fit in elevation only) or Plane. No default.
FLATMETH = _CHAR (Read)
Method to use to calculate the flatfield solution. Options are POLYNOMIAL and TABLE.
Polynomial fits a polynomial to the measured signal. Table uses an interpolation scheme
between the measurements to determine the power. [POLYNOMIAL]
FLATORDER =
_INTEGER (Read)
The order of polynomial to use when choosing POLYNOMIAL method. [1]
FLATSNR = _DOUBLE (Read)
Signal-to-noise ratio threshold to use when filtering the
responsivity data to determine valid bolometers for the flatfield. [3.0]
FLATUSENEXT =
_LOGICAL (Read)
If true the previous and following flatfield will be used to determine the
overall flatfield to apply to a sequence. If false only the previous flatfield will be used. A null
default will use both flatfields for data when we did not heater track at the end, and will use
a single flatfield when we did heater track. The parameter value is not sticky and will
revert to the default unless explicitly over-ridden. [!]
GROUP = _LOGICAL (Read)
If
true, group related files together for processing as a single data set, else process each file
independently. [FALSE]
IN = NDF (Read)
Input file(s).
METHOD = _CHAR (Read)
Sky removal method, either POLY or PLANE.
MSG_FILTER = _CHAR (Read)
Control
the verbosity of the application. Values can be NONE (no messages), QUIET (minimal
messages), NORMAL, VERBOSE, DEBUG or ALL. [NORMAL]
OUT = NDF (Write)
Output
file(s)
OUTFILES = LITERAL (Write)
The name of text file to create, in which to put
the names of all the output NDFs created by this application (one per line). If a null (!)
value is supplied no file is created. [!]
RESIST = GROUP (Read)
A group expression
containing the resistor settings for each bolometer. Usually specified as a text file using "
^
"
syntax. An
example can be found in $STARLINK_DIR/share/smurf/resist.cfg [$STARLINK_DIR/share/smurf/resist.cfg]
RESPMASK = _LOGICAL (Read)
If true, responsivity data will be used to mask bolometer data
when calculating the flatfield. [TRUE]
