Table 2.

Data and results of the HI observations with VLA/EVLA.

Telescope/s	Velocity range (km s⁻¹)	Integration time (h)	Beam size (″×″)	Noise (mJy beam⁻¹, 1σ)	N_HI limit (10¹⁹ cm⁻², 5σ)	M_HI limit (10⁶ M_⊙, 5σ)
VLA^a	1249.5−1895.2	10	27.1 × 23.6	0.31	2.68	1.5
EVLA^b	1330−1700	13	37.6 × 20.0	0.84	6.19	4.1
VLA + EVLA	1330−1700	19	28.0 × 28.0	0.25	1.78	1.4
VLA + EVLA + WF^c	1330−1700	19	28.0 × 28.0	0.13	0.89	0.7

Notes.

^(a)

3 h in D configuration, 7 h in C configuration. The original channel width is 10.4 km s⁻¹ (48.8 kHz).

^(b)

3 h in D configuration, 10 h in C configuration. The original channel width of 3.3 km s⁻¹ was smoothed o 10 km s⁻¹ (48 kHz) for the current calibration.

^(c)

Wavelet filtering (WF) applied to the VLA + EVLA data.
