Changes in Version 1.2

New Tasks

• Sky removal for SCAN map is now available using the calcsky task.

• Dual beam images taken using the new SCAN map observing mode can now be reduced using the remdbm task (also uses scumakewt).

• The offset between the arrays can be compensated for by using change_nacentre.

• Noise data can now be displayed with scunoise.

• Bolometer weights can be set with setbolwt.

Changes to existing tasks

• scucat can now accept a comma separated list of input files or a text file containing a list of files rather than having to supply one at a time. Also, there is now a METHOD option in scucat to control whether bolometers are treated independently or combined regardless of bolometer name.

• scuphot can now propagate all samples to the output file. This is necessary for observations where the number of integrations is small and the variance can not be calculated reliably.

• scan_rlb now has two extra modes for baseline removal (MEAN and MEDIAN).

• A Gaussian regridding option has been added to rebin (bolrebin, intrebin). Also, the radius and footprint size of the convolution functions can now be configured.

• A median regridding option is available. This option simply calculates the median value of all points in an output cell.

• A histogram of the distribution of data samples on the output image can be obtained with the TIMES parameter in rebin.

• Bolometer weighting has been added to rebin. This is still in alpha test since it has been shown not to conserve flux for small data sets (for larger datasets - hours - there is a signal-to-noise gain without turning off bad pixels).

• skydip now provides an estimate of the errors.

Minor fixes

• despike can now be told to write output files automatically via the DEFOUT parameter.

• scuclip now performs an iterative clip by default.

• Units are propagated through scuphot.

• sdip now resets the linplot colour settings to their original values after use.

• The size of the 'IN' parameter has been increased in change_quality and change_data.

• A memory leak has been fixed in despike.
