---++ Howto create FITS images/spectra to be VO-compatible

FITS format is a popular output used in astronomy for spectra and images. FITS recommendations when applied enable to make a clean mapping between FITS header and *ObsCore DM*.
---+++ Mapping FITS with ObsCore
<p dir="ltr">Some Obscore items can be <span style="background-color: transparent;">assigned by provider (i.e.: obsid, access_estimated_size, ..) and other can be detected in FITS using d</span><span style="background-color: transparent;">ifferent keywords. <br />We can classify them into 3 categories (ordered by relevance):</span></p>

   1 WCS keywords <br />Available for different topics (position, electromagnetics band..). WCS is a serialisation based on FITS keywords that make a bijection between a simple set of values and the true values (see the official document: https://fits.gsfc.nasa.gov/fits_wcs.html <span style="background-color: transparent;">)<br /></span>An automated workflow requires all WCS keywords :<br />i.e.: CRVAL, CTYPE, CRPIX, CDELT ,CUNIT, [CDi_j]
