cpl_table* muse_geo_table::table

The geometry table.

This type of table is used to define the location of all slices of MUSE within the field of view. It is used to create pixel tables.

The geometry table has the following columns

Mandatory columns:

  • MUSE_GEOTABLE_FIELD: sub-field (IFU / channel) number
  • MUSE_GEOTABLE_CCD: the slice number on the CCD, counted from left to right
  • MUSE_GEOTABLE_SKY: the slice number on the sky
  • MUSE_GEOTABLE_X: x position within field of view
  • MUSE_GEOTABLE_Y: y position within field of view
  • MUSE_GEOTABLE_ANGLE: rotation angle of slice
  • MUSE_GEOTABLE_WIDTH: width of slice within field of view

Extra columns to carry error estimates of the main columns:

  • MUSE_GEOTABLE_X"err": error estimated of x position within field of view
  • MUSE_GEOTABLE_Y"err": error estimate of y position within field of view
  • MUSE_GEOTABLE_ANGLE"err": error estimate of rotation angle
  • MUSE_GEOTABLE_WIDTH"err": error estimate of slice width

Extra columns initially created to support deriving the mandatory coordinates (these disappear during processing and are usually only saved to disk for debugging purposes):

  • 'stack': slicer stack that this slice belongs to (optical numbering)
  • 'spot': spot number in this slice
  • 'xrel': x offset of this spot relative to the slice center
  • 'xrelerr': error of the relative x offset of this spot
  • 'xc': x center of this spot on the CCD
  • 'yc': y center of this spot on the CCD
  • 'dxl': distance to left edge of slice on the CCD
  • 'dxr': distance to right edge of slice on the CCD
  • 'dx': pinhole distance in x on the CCD
  • 'dxerr': error estimate of the pinhole distance in x on the CCD
  • 'vpos': (averaged) vertical position of the mask
  • 'vposerr': error estimated of the (averaged) vertical position of the mask
  • 'flux': flux of the spot as integrated on the CCD image
  • 'lambda': wavelength
