Current (4/2016) handling of FITS metadata includes:
- Extra information in the file description field which shows up on the cards
- The addition of a
FITS filetag
-
Reference document for the File level metadata BRD
- Example dataset containing a FITS file: https://dataverse.harvard.edu/dataset.xhtml?persistentId=hdl:10904/10065
- The JSON metadata from the Dataset above:
- From the Dataverse native API:
- (!)Doesn't include file tags

The line profiles of HI in Ophiuchus reveal a strong and extensive HI Narrow SelfAbsorption (HINSA; Li & Goldsmith 2003) component, which is well correlated with molecular emission.</p> <p><b>Telescope:</b><br /> <a href=\"http://www.gb.nrao.edu/GBT/GBT.shtml\">GBT</a></p> <p><b>Status:</b><br /> Complete.</p> <p><b>Areal Coverage:</b><br /> 5 square degrees</p> <p><b>Noise Properties: </b><br /> 1\n-sigma rms/channel: 0.15 K</p> <p><b>Sampling:</b><br /> On-the-fly mapping and frequency switching with a 1 MHz throw were used together with a data dumping rate of twice the Nyquist sampling rate, i.e. 4 dumps as the telescope moves over a whole beam. The 12.5 MHz total bandwidth mode of the GBT Spectrometer was used with two spectral windows, one at 1420.4 MHz for HI, the other centered at 1666.4 MHz for the two OH lambda-doubling lines (not available here). The spectral resolution is 0.32 k\nm s<sup>-1</sup>. </p> <p><b>Comments on Reduction:</b><br /> During reduction, frequency-switched data at both frequencies (+/- frequency throw) were treated independently because of instrument baseline stability.</p>"
