update to socetframesettings

[thareUSGS]

During the write of the ISD (keywords.lis) file we need to add two more keywords. These make sense to be towards the top of the file - perhaps just under "SENSOR_TYPE" and "SENDOR_MODE". The two keywords are:

SEMI_MAJOR_AXIS
ECCENTRICITY

Perhaps some pseudo code. I have no idea if this is the correct method to grab equatorial and polar radii from a level 0 or 1 cube.

    if (mapping.hasKeyword("EquatorialRadius") && mapping.hasKeyword("PolarRadius")) {
      m_equatorialRadius = new Distance(toDouble(mapping["EquatorialRadius"][0]),
                                        Distance::Meters);
      m_polarRadius = new Distance(toDouble(mapping["PolarRadius"][0]),
                                   Distance::Meters);
    }
    else {
      try {
        PvlGroup radiiGrp = Target::radiiGroup(mapping["TargetName"][0]);
        m_equatorialRadius = new Distance(toDouble(radiiGrp["EquatorialRadius"][0]),
                                          Distance::Meters);
        m_polarRadius = new Distance(toDouble(radiiGrp["PolarRadius"][0]),
                                     Distance::Meters);
      }
      catch (IException &e) {
        QString msg = "Unable to grab radii from cube.";
        throw IException(e, IException::Unknown, msg, _FILEINFO_);
      }
    }

     m_eccentricity = 1.0 -
                      (m_polarRadius * m_polarRadius) /
                      (m_equatorialRadius * m_equatorialRadius);
     m_eccentricity = sqrt(m_eccentricity);

so:
SEMI_MAJOR_AXIS m_equatorialRadius
ECCENTRICITY m_eccentricity

@thareUSGS Can you make a Redmine ticket for this and #9 in ISIS

[jessemapel]

Changes are here https://github.com/jessemapel/ISIS3/tree/socetkeys

[thareUSGS]

added redmine ticket: https://isis.astrogeology.usgs.gov/fixit/issues/5363

[thareUSGS]

changes were made and can be viewed but the frame import in Socet Set or GXP will probably not use these keys. While it shouldn't hurt, they are deemed unnecessary for now for the framing cameras.
