C Release Notes—V1.2

C.1 New Commands

The following new script has been added:

trendview

Plots multiple spectra from a cube overlaying fitted trends and spectral-feature mask. It enables assessment of baseline subtraction and feature masking.

C.2 Modified Commands

The following applications have been modified:

• peakmap now has a -a option to inspect and approve the fit at each spatial pixel. There is also a -l option to log the Gaussian fit parameters and their errors in a Small Text List file.

  It inteprets a non-positive number of contours to mean no contour overlay required. There is a new -ci option to specify the colour index of contours.

  It permits case-insensitive responses to prompts except where a prompt requires a file name.

  A bug has been fixed that caused the peak-height error to be stored within the output NDF ’s VARIANCE component, instead of the actual variances.

• velmap now has a -a option to inpsect and approve the fit at each spatial pixel. There is also a -l option to log the Gaussian fit parameters and their errors in a Small Text List file.

  It permits case-insensitive responses to prompts except where a prompt requires a file name.

  It now recognises DSBSPECTRUM as a valid spectral domain.

  A number of bugs were fixed: the velocity variance is stored in the output NDF VARIANCE (previously the velocity error had been supplied); the WCS Frame is reset before re-plotting in final individual-pixel refit loop (previously the wrong spectral co-ordinate could be plotted); and the logic for deciding whether to create or switch WCS Frames is disentangled enabling DSBSPECTRUM data to be used.
