Table Header

In the table below, the values in the flags field is a bit mask with the following enumerated types:

typedef enum arRosatFlags
{
  AR_ROSAT_FLAG_NEARBY       =   0x1, // Nearby sources affecting SASS flux
                                      // determination.
  AR_ROSAT_FLAG_POSITION     =   0x2, // Possible problem with position
                                      // determination.
  AR_ROSAT_FLAG_EXTENDED     =   0x4, // Extended beyond SASS extraction radius.
  AR_ROSAT_FLAG_COMPLEX      =   0x8, // Complex diffuse emission pattern.
  AR_ROSAT_FLAG_MISSED       =  0x10, // Source missed by SASS.
  AR_ROSAT_FLAG_RECALCULATED =  0x20, // Source counts and extraction radius
                                      // recalculated.
