This script attempts to automate the first 3 steps of scuba data reduction. This script runs reduce_switch, change_flat (if requested), flatfield on the data. Then for each sub-instrument extinction, scuphot (if a photometry observation), remsky (if requested) and rebin (if requested) are used. The output name for each task is related to the task and current sub-instrument (see Notes).

scuquick

When run this way, reduce_switch will ask for the input file name and for the output root name. flatfield will then run followed by extinction on each sub-instrument. Each task will ask questions as needed.

scuquick $-$quick

Same as scuquick except that defaults will be assumed for all parameters that have defaults.

scuquick $-$rebin

Process as for scuquick except that rebin is run on each sub-instrument.

scuquick $-$quick jun02_dem_0002

Process the input file jun02_dem_0002.sdf, accepting all defaults.

scuquick $-$quick jun02_dem_0003 MSG_FILTER=QUIET

Process jun02_dem_0003.sdf, accepting all defaults and turning off all but the most important messages from the SURF tasks.

scuquick $-$quick $-$notau $-$rebin temp OUT=root

Process temp.sdf with zero extinction correction, accept all defaults, use ‘root’ as the default filename and regrid.

scuquick $-$remsky $-$change_flat $--$sub=long

Run the remsky and change_flat tasks in addition to the standard tasks but only process the LONG sub-instrument.

scuquick $-$rebin $-$quick MSG_FILTER=QUIET PIXSIZE_OUT=1 test OUT=temp

Process test.sdf. Accept all defaults. Use ‘temp’ as the filename root. Regrid all data onto a 1 arcsecond grid. Hide all messages from the SURF tasks.

Given a rootname (specified with OUT=root or by accepting the default value offered by reduce_switch) SCUQUICK produces the following files (identical to the files produced with SCUBA_SUFFIX=long):

• root.sdf from reduce_switch

• root_flat.sdf from flatfield

• root_$<$sub$>$_ext.sdf from extinction (one for each sub)

• root_$<$sub$>$_sky.sdf from remsky (with the –remsky switch)

• root_$<$sub$>$_reb.sdf from rebin (with the –rebin switch)

• root_$<$sub$>$_pht.sdf from scuphot (if processing a PHOTOM observation)

• root_$<$sub$>$_pht.dat from scuphot (if processing a PHOTOM observation)

Where $<$sub$>$ is the first three letters of the sub-instrument name. Using the $-$tau switch is dangerous when processing multiple sub-instruments since the extinction changes with wavelength.

• Command line options can be abbreviated.

• Skydip observations are recognised.

• Options that take values can be used either as ‘$-$flag option’ or as ‘$--$flag=option’

• The NDF perl module must exist (this should be installed by your system administrator if it is missing).
