srcinfov: compute position of SouRCe in Field Of View

• SYNOPSIS
  
      srcinfov strra=<ra> strdec=<dec> apos=<apos> withsrccoord=true|false
               srcra=<ra> srcdec=<dec>
  
• DESCRIPTION
  srcinfov computes for each instrument the position of a given celestial source in the field of view (in TELCOORD coordinates). Input is the satellite attitude in terms of Right Ascension/Declination of the star tracker viewing direction and astronomical position angle [deg]. The boolean parameter withsrccoord determines whether the J2000 equatorial coordinates of the celestial source are explicitly provided through the parameters srcra and srcdec or taken as the star tracker viewing direction. Right Ascension/Declination of the star tracker boresight and the celestial source can be entered in either of the forms

        23h59m48.12s / 45o38'14.55"
  

  or decimal degrees:

        123.23445 / 45.238474
