The cosmicrays task is throwing segmentation violations every time it is run. Noticed on v2.16 but occurs on 2.15.x. Had to go back to 2.14.1 before it worked. I'm running a 64-bit Ubuntu machine, if that helps. The error can be reproduced using dev$pix as the input.Also something confusing is going on with the help databases for this task. Using ctio's apropos task, you get[code:1:969e4ddc66]cosmicrays - Detect and replace cosmic rays (noao.imred.ccdred)
cosmicrays - Detect and replace cosmic rays (noao.imred.generic)
[/code:1:969e4ddc66]yet neither of those packages contain the cosmicrays task, which is (currently) located in the imred.crutil package.Also, running [code:1:969e4ddc66]find . -name "cosmicrays*"[/code:1:969e4ddc66] at the top of the IRAF tree finds these files which seem to be leftovers of some sort.[code:1:969e4ddc66]./noao/imred/ccdred/src/cosmic/cosmicrays.hlp
./noao/imred/ccdred/cosmicrays.par
./noao/imred/quadred/src/quad/doc/cosmicrays.hlp[/code:1:969e4ddc66]Cheers,

A bug was recently fixed in the task that may solve this, you can get a new binary fromftp://iraf.noao.edu/iraf/v216/support/linux64/x_crutil.eInstall in the noao$bin/linux64 directory.[quote:90480e61a9]Also something confusing is going on with the help databases for this task. Using ctio's apropos task, you get[/quote:90480e61a9]The CTIO package has been orphaned for a while and the APROPOS task hasn't been touched since 1991. You can try using MKAPROPOS to rebuild the database it uses, otherwise I'd chalk it up to changes in the help code over the last two decades. The core system provides a REFERENCES task that serves the same purpose.Tasks are often included in multiple packages, duplicate help pages come about when a task used to live in an external package and then gets moved to the core system. Differences in the help page may reflect differences in the code itself (e.g. the old extpkg version has a special parameter for some reason), but it doesn't necessarily mean it is an error.
