Atlas of Comparsion Lamp Spectra for LDSS-3

Sample LDSS-3 Arc Lamp Exposures 

 

These were taken through a  1.0 arcsecond wide slit. The top link in each box shows the Arc with lines identified in wavelenghts space and the bottom links shows the lines identify in pixel space with the axis in wavelenght (this is useful to have and idea where your object lines are in your image).

 

VPH_All arcs are all 6 seconds exposure, VPH_Blue (Blue and center slits) are 10 seconds and Red slit is 5 seconds and VPH_Red are 2 seconds exposure.

 

These Arcs were taken on December 17 2007. All spectra were taken with the He Ne Ar lamps on.

 

You may find the following FITS files useful for reference or planning. They each contain a wavelength-calibrated 1-D spectrum. These are also available on the data disks on both observer workstations in the Clay dome with their respective dispersion solutions in the database directory.

You can also download the dispersion solution for each arc from the table.
