1 Figaro - Spectroscopy Data Reduction Package Expires: ????.??.?? Figaro is a powerful and comprehensive general-purpose package for the reduction of astronomical images and spectra. It contains particularly extensive facilities for spectroscopy. Figaro is documented in SUN/86.

Bug fixes: - Corrected pointer indexing introduced while switching tasks to support 64-bit addressing, notably in ARC2D, LONGSLIT, and COMB. - Spectral-line editing restored. - LONGSLIT and ARC2D applications ha stopped operating after the merger of TWODSPEC. 2 Version 5.6-5 A bug in the movie application has been fixed. Previously the movie axis had to be shorter than the first axis. 2 Version 5.6-3 Version 5.6-3 of Figaro has recently been released. The changes in Version 5.6-3 comprise only a few minor bug fixes and enhancements, and a missing flux calibration file has been added. Brief details of the changes are given below. A C Davenhall, 9 February 2004. revised Malcolm J Currie 2004 February 17 3 Bug Fixes and Minor Enhancements GAUSS and IARC have each received both a bug fix and a minor enhancement. Consequently, there has been an equally minor revision to the description of GAUSS in the user manual. EMLT has a new NOISE keyword. If it is specified, allowance for noise is made when determining the line limits. This is intended for broad emission features or beam location rather than narrow arc lines. It defaults to the former behaviour. SDIST allows for broader spectral profiles when tracing a spectrum. There was an arbitrary cut-off of the size of the extracted cross-section to be fitted. 3 Flux Calibration Files The flux calibration file for Hiltner 102, hil102.tab, was missing. It has been added.
