PhC from Meep tutorial with MPB

Hi all,

My question is about the PhC (waveguide) found at 
http://ab-initio.mit.edu/wiki/index.php/Meep_Tutorial/Band_diagram%2C_resonant_modes%2C_and_transmission_in_a_holey_waveguide 
. According to Meep, the first TE bandgap should lie between (approx.) 
0.2 and 0.3 .
However, when I try to calculate the band structure using MPB, I get the 
following results:

Gap from band 1 (0.160365111747009) to band 2 (0.246811853360678), 
42.4615088875704%
Gap from band 2 (0.330543886888107) to band 3 (0.400882050577518), 
19.2331608947669%
Gap from band 5 (0.458936326035846) to band 6 (0.513722725411668), 
11.2652834092867%

Is the difference between these two results caused only by the finite 
nature of the structure in Meep (as opposed to an infinite PhC in MPB) 
or is there more to it? Thanks in advance,

Elewout
