Although ROBOT can read up to 4 columns (x, y, y error, x
error) of input you need not use all columns. E.g. you can just have a
file with x and y points and the errors will be taken as 0. If you have
a file with only one column this will be taken as y values and the x
values will be set to the sequence numbers of the data. If you want
ROBOT to read different columns as the x, y values etc. use the
command:
TABLE - the argument for this is four numbers which give the column
numbers that the x, y, y error and x error values are found in. The
default is 1 2 3 4. Note that using this command you can select up to
four columns from an input file which contains more than four
columns.
INFILENOTEXT - specifies that the input file doesn't have the three
lines of text at the top.
INFILETEXT - specifies that the input file does have three lines of
text header (default).
INFILENOTEXT and INFILETEXT must be used before DATAFILE.
OVERPLOT - read in new data file, similar to DATAFILE except that the
plotting area etc. are not redefined.
TYPE - means that ROBOT will directly read data - i.e. from the
terminal for interactive use. This command can also be used
to include data directly in a command file.
Input format is the same as that for DATAFILE.
OVERTYPE - as TYPE but doesn't rescale the plotting area.
TYPEMORE/MORETYPE - like TYPE but reads in additional data and adds to
existing data set.
PLOTMORE/MOREPLOT - like DATAFILE but reads in additional data and adds to
existing data set.
FITS - reads a cross section of a FITS image. Argument: rows to
add up to produce the cross section.
FITSX - as FITS but sums across columns.
