IF_FILLER::get_uniques private

function IF_FILLER::get_uniques(arr, count)

Sorts and uniques an array

Returns: uniqe values of array

Parameters

IF_FILLER::get_row_value private

function IF_FILLER::get_row_value(row, tag_name, virtuals, names, default_value)

Method for attempting to extract a value from an sdfits row. If the row contains the tag name requested, that value is passed back. If that tag name actually specifies a keyword in the extension-header, and NOT a column, then that value is returned. Finally, if the tag name mathes one of the expected column names that were not found in this extension, the default value is returned.

Returns: either the value of row.tag_name, virtauls.tag_name, or default_value

Parameters

row
in
struct structure that mirrors a row in an sdfits file

tag_name
in
string name of the value that we want to retrieve

virtuals
in
struct struct giving the keyword-values found in the file-extension

names
in
struct struct contiaining pointers to the names of columns in the row, missing columns, and tag names in the virtuals struct

default_value
in
value to be returned if the tag_name is of a missing column

IF_FILLER::get_col_variability private

function IF_FILLER::get_col_variability(rows, tag_name, names, default_value)

Given rows from an sdfits file, how much does the value of a given column vary? Used when translating contents of an sdfits file into contents of the index file.

Returns: the variablity of this column in the fits file

Parameters

rows
in
array array of structures mirroring sdfits rows

tag_name
in
string column in the sdfits rows we are querying

names
in
struct structure containing pointers to the list of row columns, missing cols, and header keywords

default_value
in
if the tag_name is not found in the rows or as a keyword, use this as the variability

IF_FILLER::find_matching_polarizations

pol
