Function Documentation

int count_records	(	char *	filename,
		int	reclen
	)

Count the number of records in the given file for the given record length

Referenced by create_merge_table(), and prepare_detections_list().

double get_conv

(

char *

units

)

Return numeric scaling factor associated with the input units.

Referenced by gobble().

void get_coordinfo	(	PyObject *	arg,
		coordset *	coord
	)

Extract coordinate (eg RA and DEC) information from the Python tuple object and place it in the structure. The information to be extract comprises: the first byte on the record, the word size, and a string representing the units

Referenced by get_recinfo().

void get_recinfo	(	PyObject *	arg,
		char *	filename,
		coordset *	coord1,
		coordset *	coord2,
		int *	reclen
	)

From the input python tuple object, extract the filename, the coordinate set structures for RA and DEC and the record length

References get_coordinfo().

void gobble	(	char *	filename,
		coordset	coord1,
		coordset	coord2,
		int	reclen,
		CartesianSet	cart[],
		IndexedList	declist[]
	)

Read the entire file into an array of cartesion coordinates and an indexed list of declinations

char* makeoutname	(	int	i1,
		int	i2,
		char *	path
	)

Make up a string giving the name of the out pointer files for input passbands i1 and i2

Referenced by multiPair().

void read_pointers	(	char *	filename,
		int *	pp,
		int	nrec
	)

Read the pointer array from the given filename.

Referenced by create_merge_table().

void write_pointers	(	char *	filename,
		int *	pp,
		int	nrec
	)

Write the pointer array to the given file name.
