The input specifier determines the input table on which the processing will be performed. It has the form:
[-ifmt <in-format> [-stream]] [<in-table>]which is interpreted as follows:
-ifmt <in-format>
<in-format>
is the name of one of the input formats.
If the -ifmt
flag is not used, auto format-detection
is used (OK for FITS and VOTables). For other formats, such as CSV
or ASCII, you must name a format using this flag.
-stream
-ifmt
flag in this case.
Depending on the required operations and processing mode, this may fail
(sometimes you need to read the input file more than once).
<in-table>
-stream
is implicit).
