I'm trying to use write_csv and am having problems using the header keyword. It works fine if I only write one variable and have one header, but as soon as I add a second variable and a second string to the header array I get an error message that says 'HEADER must be a string array of length equal to the number of columns'. From what I can tell my string array is the same length as the number of variables I'm trying to write.
header = ['Altitudes','DEM_gnd_alt']
write_csv, 'Seac4rs_DIAL_DC8_20130808_RA_Nav.csv', alt, demgndalt, header=header
Can someone please help? Thanks.

This is what I get from help, alt, demgndalt
ALT FLOAT = Array[1, 678]
DEMGNDALT FLOAT = Array[2710]
I guess the problem is because alt is 2D and my other variable is only 1D. I suppose I need to make them the same size, correct? I also get the same error message though when I use two 2D variables though
O3 DOUBLE = Array[2710, 678]
SA DOUBLE = Array[2710, 678]
HEADER STRING = Array[2]
So now I'm confused again.
Thanks.

Sorry, my mistake. The 678 goes with the 2D array. That is the number of altitudes for the 2710 data points. I'll have to find the doc and read more. Would you suggest just using printf to output the data to csv file?
