Repository 2 of 2 of the Level 0 (raw FITS) images from the DMI Mauna Loa Earthshine telescope experiment (2010-2012)

<h2>Raw data upload</h2> <p>These are tar files of the raw data obtained with the earthshine refractor conceived, designed and built by Danish Meteorological Institute and Lunds Observatory and operated on Mauna Loa at the NOAA observatory during 2011-2012.</p> <p>The present doi relates to one of two - each one holds&nbsp; roughly 50Gb tar file. Get all&nbsp; for the complete dataset. The other doi is: 10.5281/zenodo.11442378</p> <p>The data are in the form of FITS files. There are data for 5 different photometric filters - Johnson B and V and then 3 red or nIR filters - IRCUT, VE1 and VE2. Some frames are without filters.</p> <p>Examples:</p> <p>2455945.1760145MOON_B_AIR.fits.gz - image of the&nbsp;Moon through the B filter</p> <p>2455945.0413946DARK_DARK.fits.gz - a DARK frame image taken with same exposure time as the adjacent MOON image.&nbsp;<br>A DARK is typically taken before and after all MOON images.</p> <p>The file-naming strategy for the file inside the archive files is simple - names start with the (fractional) Julian day of the observation, followed by target name and two indicators of the filters or other light-path devices that were used, e.g.: _VE1_AIR indicates the VE1 colour filter with just 'air' (ie nothing)&nbsp; in the second option. The second option may include names of knife-edge devices or neutral density filters that could be inserted.</p> <p>There are also some FLAT images taken on inside of dome or of the sky or of the Hohlraum source.</p> <p>The MOON images may well be 100-image 3D-cubes taken within a minute or two.</p> <p>Future upgrades (in new dois, but in this Community) will include dark-frame subtracted, aligned and averaged images (Level 1). A Level 2 may include actual model fits of the full lunar disks, in which terrestrial albedo is a model-parameter.</p> <p>The file called "index_justJD.csv" lists which Julian days are present in which archive file. Note that some days are spread over several tar files.</p> <p>The images were acquired with the remotely-operated telescope by&nbsp; Peter Thejll, Hans Gleinser, Chris Flynn, as well as Henriette Schwarz.</p> <p>Notes updated May 3 2024.</p> <p>Peter Thejll</p> <p>write pth@dmi.dk for queries</p>
