Spherical harmonic models of the shape of (433) Eros
<p>This archive contains two spherical harmonic models of the shape of asteroid 433 Eros. One model is based on laser altimetry from the instrument NLR and the other is based on a stereo photoclinometry shape.</p> <p>The data used to generate the model based on laser altimetery were taken from the file <code>nlr125ar.img</code> on <a href="https://sbnarchive.psi.edu/pds3/near/NEAR_A_NLR_6_EROS_MAPS_MODELS_V1_0/data/img/">NASA's PDS website</a>. This image file was first converted to netcdf format using the <a href="https://www.generic-mapping-tools.org/">generic-mapping-tools</a> function <code>xyz2grd</code>, and the resulting pixel registed map was then converted to a gridline registration using the function <code>grdsample</code>. Following this, the resulting netcdf file was read into the <a href="https://shtools.github.io/SHTOOLS/index.html">pyshtools</a> software and expanded into spherical harmonics using the function <code>SHCoeffs.expand()</code>. The spherical harmonic functions were chosen to be "4pi" normalized and to exclude the Condon-Shortley phase factor of (-1)<sup>m</sup>. The units of the coefficients are meters.</p> <p>The data used to generate the model based on the stereo photoclinometric shape model were taken from the file <code>quad512q.tab</code> on <a href="https://sbnarchive.psi.edu/pds4/non_mission/gaskell.ast-eros.shape-model_V1_1/data/quad/">NASA's PDS website</a>. The vertices from the ICQ shape model with Q=512 were first converted from Cartesian to spherical coordinates, from which a regular gridline registered netcdf file was created using the <a href="https://www.generic-mapping-tools.org/">generic-mapping-tools</a> function <code>surface</code> with a tension of 0.6 and with a grid spacing of 0.17578125 degrees. This file was then read into the <a href="https://shtools.github.io/SHTOOLS/index.html">pyshtools</a> software and expanded into spherical harmonics in the same manner as the NLA based model.</p> <p>The two files in this archive are</p> <ul> <li>Eros_NLR_shape_719.bshc.gz</li> <li>Eros_SPC_shape_511.bshc.gz</li> </ul> <p>The numbers 719 and 511 in the filename refer to the maximum spherical harmonic degree of file, which corresponds to effective spatial resolutions of 8 and ~5.7 pixels per degree, respectively. The files are stored in the binary "bshc" format as described in the pyshtools documentation and are furthermore compressed using gzip.</p>

Translated spherical harmonic gravitational field models for Phobos and 433 Eros
<p>The dataset contains the spherical harmonic gravitational field models for the Martian moon Phobos and the asteroid 433 Eros, which are translated from the original models derived in the respective coordinate systems.</p> <p>The gravity model files contain the normalized spherical harmonic coefficients in the standard format in the folder "gravity". The files named with the prefix "sphcfs\_" are for: 1. base models tied to the respective shape models of Phobos and Eros; 2. four translated models for the northern and southern halves of Phobos and Eros. The models are derived via boundary-value problems. The translated models are each accompanied by an analytically transformed model for comparison. The corresponding data files are identified with the prefix "tsphcfs\_".</p> <p>The triangulated shape model for Phobos interpolated using the spherical harmonic series by Willner et al. (2014), Planetary and Space Science, vol. 102, pp. 51-59, DOI:10.1016/j.pss.2013.12.006 is given in the ".obj" format. The shape model for Eros by Thomas et al. (2002), Icarus, vol. 155, pp. 18-37, DOI:10.1006/icar.2001.6755 used in the study belongs to the ``NEAR Collected Shape and Gravity Models'' (NEAR-A-5-COLLECTED-MODELS-V1.0) at https://sbn.psi.edu/pds/resource/nearbrowse.html (retrieved in Mar. 2024), and is not included. The dissected shape models are provided for both objects, which are used for model evaluation over the northern and southern halves of the bodies.</p> <p>The parameters of the Brillouin spheres are provided in the folder "sphere".</p> <p>The numerical results in the folder "result" are modeled gravitational potentials alongside the true values around and on the surface of the bodies. The results for the ellipsoidal harmonic models are provided for comparison.</p>
