Data Reduction Pipeline for EMIR; a near-IR multiobject spectrograph for the Spanish 10m telescope
EMIR (Espectrografo Multiobjeto Infrarrojo) is a near-infrared wide-field camera and multi-object spectrograph to be built for the 10.4m Spanish telescope (Gran...
FRIDA (inFRared Imager and Dissector for the Adaptive optics system of the GTC) will be a NIR (1-2.5 μm) imager and Integral Field Unit spectrograph to operate...
Data treatment towards the ELT age. The ESPRESSO case
Several ambitious scientific projects are currently pushing the limits of astrophysical spectroscopy, in terms of wavelength accuracy and long-term stability...
The photometric decay of sunspots is studied in some detail. Aspects related to leader vs. follower sunspot decay are presented and our current understanding of...
Various possible decay laws (exponential, linear, parabolic) are tried to fit the observational material. The dependence of the decay rates on the spot's...
The global behavior and fine structure of the distribution of sunspot decay rates from activity cycle 13 to 20 are presented. It is shown that the distribution...
