Hello,

I have a sample masked array data as shown below.

1-) When I list the whole array I see the fill value correctly. However below that line, when I do access the 5th element, fill_value flies upto 1e+20. What might be wrong here?

I[5]: c.data['Air_Temp']
O[5]:
masked_array(data = [13.1509 13.1309 13.1278 13.1542 -- 13.1539 13.1387 -- -- -- 13.1107
13.1351 13.2073 13.2562 13.3533 13.3889 13.4067 13.2938 13.1962 13.1248
13.0411 12.9534 12.8354 12.7392 12.6725],
             mask = [False False False False True False False True True True False False
False False False False False False False False False False False False
False],
       fill_value = 999999.9999)

I[6]: c.data['Air_Temp'][4]
O[6]:
masked_array(data = --,
             mask = True,
       fill_value = 1e+20)

2-) What is wrong with the arccos calculation? Should not that result the same as with cos(d) result?

I[9]: d = c.data['Air_Temp'][4]

I[11]: cos(d)
O[11]:
masked_array(data = --,
             mask = True,
       fill_value = 1e+20)

I[12]: arccos(d)
O[12]:
masked_array(data = 1.57079632679,
             mask = False,
       fill_value = 1e+20)

Any ideas?
