Comparison lamp atlas (CuHeNeAr)

The comparison lamp atlas (CuHeNeAr) for the Boller & Chivens spectrograph was recently updated. The report for this update can be found here (download report - Spanish version). 

The spectrum in FITS format for IRAF can be downloaded here. The spectral lines of Cu, He, Ne, and Ar identified in this spectrum can be consulted in the folowing list (download). The list of spurious lines (yellow) from other spectral orders that should not be used during the line identificacition process for calibration can be downloaded here.

The lamp spectrum as acquired (M. Richer 2005) in FITS forma for IRAF can be downloaded here. 

Below, users can find charts for identifying the lines of the spectrograph´s comparison lamp. to veiw each chart in detail o download it, click on the image.

La RUCA II

The La Ruca II instrument is a filter wheel specifically designed for conducting astronomical observations in direct imaging. This device allows the use of up to eight different filters, which can be automatically exchanged without the need for manual intervention. The UBVRI (Johnson-Cousins) filters are installed by default. La Ruca II is currently assigned to the 1.5 m telescope; however, it is compatible with the 2.1 m and 84 cm telescopes at the National Astronomical Observatory of San Pedro Mártir, offering great versatility.

OPTICAM

italiana

This instrument was designed to perform rapid photometry on three channels simultaneously.

It has a system of three fast detectors (with high temporal resolution) that allows simultaneous optical images in 3 colors. These detectors have CMOS technology (Andor Zyla 4.2-Plus) and the instrument also has a set of filters Astrodon Gen2 SDSS u’ g’ r’ i’ z’ that allow coverage in the range of 320 to 1,100 nm.

OPTICAM nominally allows exposures on the order of sub-seconds. Given its instrumental design, a wide range of rapidly changing astrophysical sources can be observed with this instrument.
