*After you splot a spectra and use the function mode 'f', the menu shown in the graphics window ends with
[code:1:67a2b630f5]p=+k m=*k +,-,*,/=2spec ops[/code:1:67a2b630f5]
I would recommend it be changed to
[code:1:67a2b630f5]p+=k m*=k +,-,*,/=spec2 ops[/code:1:67a2b630f5]
because spec2 is the actual second spectrum name used by the task and help file and the "+="-style syntax is more standard (and used by IRAF).Some [b:67a2b630f5]splot[/b:67a2b630f5] help fixes:*The task help lists "wcreset" as one of the "options" but it the rest of the documentation uses "wreset".*In the epar description for wavelength, there is a colon (Dispersion coordinate
that shouldn't be there.*In the splot help, the options parameter has [b:67a2b630f5]The "overplot" options overplots[/b:67a2b630f5] but should be [b:67a2b630f5]The "overplot" option overplots[/b:67a2b630f5].*For the description of the mag parameter, the description should start on the next line to match the other parameters. The last sentence ends strangely ("is in" probably should just be "in") . Plus it needs a period.*The DESCRIPTION section's 2nd word, "option" , is used to describe the "options" parameter. Later in this same sentence there is a double a ("a a").*In the 5th paragraph of the DESCRIPTION section, "replace then in the new output image"..... I think should be "replace them in the new output image". (This sentence really could use a comma too after "saved".)*In the DESCRIPTION section's discussion of the keystrokes, the 'a' (expand) section has "See also 'w', and 'z'.", which has an unwanted comma.*In the 'f' (function mode) section, uncapitalize function in "q Quit Function mode".*In the "g Get another spectrum." section, the last two words, "is necessary" probably should be "as necessary".*In the 't' section (ICFIT) the '-' description formating is offset wrt the other descriptions.*For the ',' command (Shift the graph window to the left), it should not have apostrophes around the comma, cf with the '.' command just below.*In the EXAMPLES section, there is a "Therefore it these examples..." that should be "Therefore these examples...".JasonPS I've been using splot a lot recently and it occurred to me that it'd be good if IRAF had a default spectrum similar to dev$pix that could be used to help report problems with 1D tasks.
