These C++ routines can be found in SPio.h and SPio.cxx and are not
available from Python.
template <class T> T SPreadKey(CCfits::PHDU& primary, const string Keyname,
const T DefValue)
Read a keyword value from the primary header.
template <class T> T SPreadKey(CCfits::ExtHDU& ext, const string Keyname,
const T DefValue)
Read a keyword value from an extension header.
template <class T> T SPreadKey(CCfits::ExtHDU& ext, const string Keyname,
const Integer RowNumber, const T DefValue)
Read a keyword value which may be in a column for type II files.
template <class T> void SPreadCol(CCfits::ExtHDU& ext,
const string ColName,
std::valarray<T>& Data)
Read a column into a valarray.
template <class T> void SPreadCol(CCfits::ExtHDU& ext,
const string ColName,
std::vector<T>& Data)
Read a column into a vector.
void SPreadCol(CCfits::ExtHDU& ext, const string ColName,
StringVector& Data)
Read a string column into a vector (special case necessary
for a workaround in CCfits).
template <class T> void SPreadCol(CCfits::ExtHDU& ext,
const string ColName,
const Integer RowNumber,
std::valarray<T>& Data)
Read a column from a Type II file into a valarray.
template <class T> void SPreadCol(CCfits::ExtHDU& ext,
const string ColName,
const Integer RowNumber,
std::vector<T>& Data)
Read a column from a Type II file into a vector.
template <class T> void SPreadVectorCol(CCfits::ExtHDU& ext,
const string ColName,
std::vector<std::valarray<T> >& Data)
Read a vector column into a vector of valarrays.
template <class T> void SPreadVectorCol(CCfits::ExtHDU& ext,
const string ColName,
std::vector<std::vector<T> >& Data)
Read a vector column into a vector of vectors.
template <class T> void SPreadVectorColRow(CCfits::ExtHDU& ext,
const string ColName,
const Integer RowNumber,
std::valarray<T>& Data)
Read a single row of a vector column into a valarray.
template <class T> void SPreadVectorColRow(CCfits::ExtHDU& ext,
const string ColName,
const Integer RowNumber,
std::vector<T>& Data)
Read a single row of a vector column into a vector.
template <class T> void SPwriteKey(CCfits::PHDU& primary,
const string Keyname,
const T KeyValue, const string Comment)
Write a keyword to the primary header. This uses the
CONTINUE convention if KeyValue is a string and longer than
68 characters.
template <class T> void SPwriteKey(CCfits::Table& primary,
const string Keyname,
const string ColName,
const std::valarray<T>& Data,
const bool forceCol = false)
Write a column from a valarray. If the data size is 1 or all
values are the same then just write a keyword unless the
forceCol bool is true.
template <class T> void SPwriteCol(CCfits::Table& table,
const string ColName,
const std::vector<T>& Data,
const bool forceCol = false)
Write a column from a vector. If the data size is 1 or all
values are the same then just write a keyword unless the
forceCol bool is true.
template <class T> void SPwriteVectorCol(CCfits::Table& table,
const string ColName,
const std::vector<std::valarray<T> >& Data,
const bool forceCol = false)
Write a column from a vector of valarrays. If the data size
is 1 or all values are the same then just write a keyword
unless the forceCol bool is true. If all values are the same
within all valarrays then write a scalar column.
template <class T> void SPwriteVectorCol(CCfits::Table& table,
const string ColName,
const std::vector<std::vector<T> >& Data,
const bool forceCol = false)
Write a column from a vector of vectors. If the data size
is 1 or all values are the same then just write a keyword
unless the forceCol bool is true. If all values are the same
within all valarrays then write a scalar column.
template <class T> bool SPneedCol(const T& Data, bool& isvector)
Check whether a column is required and if it needs to be a
vector column. Note that T is assumed to be a valarray or
vector of a valarray of some type.
template <class T> bool SPneedCol(const T& Data)
Check whether a column is required. For this overloaded
version T is assumed to be a valarray or vector of scalar of
some type.
template <class T> bool SPneedVecCol(const T& Data)
Check whether a given column needs to be a vector. This
assumes that the column is required and cannot be replaced
by a keyword. T is assumed to be a valarray or a vector of a
valarray of some type.
StringVector SPreadAllPrimaryKeywords(const string& filename)
Real all keywords from the primary extension into a vector
of strings each of which is of format “KeyName = KeyValue”.
StringVector SPreadAllKeywords(const string& filename,
const string& hduName,
const int& hduNumber)
Real all keywords from an extension into a vector
of strings each of which is of format “KeyName = KeyValue”.
StringVector SPreadAllColumnNames(const string& filename,
const string& hduName,
const int& hduNumber)
Real all the column names from an extension into a vector
of strings.
