LUCIFER example data

The LUCIFER Team has provided the following example data sets in advance of SDT observations. The links are to .tar.gz files:

Description:

Narrowband imaging data in the Paschen gamma filter were taken on MST 2009-09-26 under photometric conditions. The images were all taken in double-correlated read (DCR) mode. The target field is the photometric standard star FS29. A dice-5 pattern was used to dither on-source, with two exposures taken at each position and saved separately. The standard star appears centered on the detector in the last pair of images.

On the same photometric night (MST 2009-09-26), broadband Ks images were taken of the photometric standard FS6. These data were also taken in DCR mode, and also in a dice-5 pattern. Integrated data, 12 exposures of 5.0 seconds, was saved for the source images and darks. As with the previous data set, the standard star appears centered on the detector in the last image. The 2.0 second dark exposures in with the Paschen gamma data can be used to dark-subtract the flats below.

Spectroscopic long-slit data with a standard set-up (210zJHK grating and N1.8 camera) in the J and K bands were taken on MST 2009-11-02. Two telluric standard stars (Hip 19799 and Hip 17707) were observed. Three dither positions along the slit were collected for each set. All spectroscopic observations were obtained through the 600 micron (one arcsec) wide slit. For the K band data the central wavelength was 2.130 microns. For the J data the central wavelength was 1.245 microns.

The calibration lamp data were taken on the previous night (MST 2009-11-01) with the same grating, slit, and camera as the telluric standards above. The J data have the same central wavelength (1.245 microns), but the K data were taken with a different central wavelength (2.1997 microns). Argon (Ar) and continuum (Halogen) data were taken for both settings.

The K band calibrations in the dataset above should be replaced with the following files, taken with the same central wavelength (2.130 microns) setting as the telluric standards.
