New concepts in CLASS
CLASS is a state-of-the-art reduction and analysis software for (sub-)millimeter spectroscopic data. It is daily used to reduce spectra acquired with the IRAM 30m telescope and with many other facilities (e.g. APEX, CSO, HHT, Effelsberg). It can also be used to reduce Herschel/HIFI data. We describe here the new concepts of data management introduced in the last 5 years to cope with the spectacular improvements of millimeter radioastronomy instrumentation (large multipixel arrays, large bandwidth receivers, high resolution spectrometers): table of contents, easy selection of data subsets, interactive visualization tools, interface to line catalogs, ...
