Calls to Chandra.Time.convert leak memory significantly enough to cause memory issues when using the FOT MATLAB Tools (specifically the Xija thermal models which use Chandra.Time to convert between MATLAB Tools times and Xija model times). The following conversion loop leaks around 2 MB of memory a second on a GRETA workstation:
import Chandra.Time
test_vals = range(100000)
for i in range(20)
a=Chandra.Time.convert(test_vals,fmt_in="secs",sys_in="utc",fmt_out="secs",sys_out="tt")
This memory leak is caused by the lack of "delete" calls in the C++ code after creating new objects with "new" statements. Specifically, adding the following statement after line 166 of axTime3.cc eliminates the memory leak experienced by the MATLAB Tools when running the Xija thermal models:
