[bug #63064] Statistics crashes when all pixels are nan

[Mohammad Akhlaghi]

Follow-up Comment #1, bug#63064 (group gnuastro):

Until the bug is fixed, the following condition can be used in a script: we
are using the shell's 'if' to check if Statistics returned successfully or
not. If not, the script can be prepared to deal with scenarios where all the
inputs are NaN.


$ if aststatistics img.fits; then echo GOOD; else echo BAD; fi
